## Problem
- workspace connection is currently failing via presigned url due to
change of attributes

## Solution
- reverting change and using eks cluster attr for hostname

## Testing
- updated unit tests
- tested locally with new vsix

…#8514)

## Problem

Console session credentials fail to work properly in two scenarios:

1. After token refresh or profile overwrite: Users encounter "Your
session has expired" errors even after successfully running aws login,
requiring manual VS Code restart without clear guidance (reported in
#8488)

2. Immediate connection use after CLI login: When users try to use a
connection immediately after aws login completes, the credential
provider was created before the CLI wrote the new login session to disk,
causing authentication failures



## Solution

- Enhanced makeConsoleSessionCredentialsProvider() to detect stale
credential scenarios and prompt for window reload

src="https://github.com/user-attachments/assets/2c0b77be-ea10-4a41-9642-29d637a03110"
/>
- Added user-friendly messages showing identity ARN after successful
login

src="https://github.com/user-attachments/assets/841721be-525d-4853-8d7a-b49f7d97c272"
/>



- Improved inline documentation explaining AWS CLI vs SDK credential
handling differences
- Added handling for does not contain login_session error when provider
is created too early
- Removed try-catch wrapper when verifying that connection exists after
CLI succeeds


## Tradeoffs

Reloading the VS Code window is a heavier UX, but it is the only
deterministic way to fully reinitialize credential providers and avoid
using stale credentials. Reloading guarantees that all in0memory
credential providers, Auth state, and AWS SDK clients are fully
reinitialized. This avoids subtle, hard-to-debug states where
credentials appear refreshed on disk but stale credentials are still
used at runtime.

The reload is user-initiated via confirmation, not automatic. For future
direction, this needs a supported Auth/provider reset mechanism to
refresh credentials without requiring a window reload.

## Testing
1. Run `npm run compile` to verify build.
2. Run `npm run package`. Manual verification of end-to-end flow
- Verified token refresh flow prompts for reload and works after reload
- Tested immediate connection use after aws login triggers appropriate
reload prompt
- Confirmed profile overwrite scenarios handle credential refresh
correctly

## Problem

After updating AWS CLI for console credentials, the success message
didn't show users which AWS CLI installation the Toolkit was actually
using. This made it unclear whether the update was successful or if
multiple CLI installations existed on the system.

This is particularly problematic for users who encountered repeated
update prompts during console credentials authentication, as they can't
verify if the correct CLI version is being used.


## Solution

- Added child process execution to run the OS-specific command (which on
Unix/macOS, where on Windows) after CLI update
- Retrieved the actual AWS CLI path that the Toolkit uses for console
credentials
- Updated the success message to display: 'AWS CLI updated successfully
to "{path}"'


This helps users immediately verify the CLI installation location and
confirms which CLI binary the Toolkit will use for console login.


### Notes

We make a display message clearer that this is about what the Toolkit
will be used going forward, not necessarily what the installer was just
installed. This helps distinguish between:
- What the installer just updated/installed
- What the Toolkit will actually use (which could be a different
installation if multiple exist)

… adding region to profile (#8522)

## Problem
- If a user picks a profile that does not have region entry from the
config file, smus tries to update the profile with selected region. But
smus is only looking for the profile in credentials file.

## Solution
- Look for profile in both config and credentials files when adding
region to profile
- Use shared parsing method to handle profiles with `profile` prefix

## Test
Updating profile with `profile` prefix in config file 

before
```
[profile configWithProfilePrefix]
AWS_ACCESS_KEY_ID=xyz        
AWS_SECRET_ACCESS_KEY=xyz              
AWS_SESSION_TOKEN=xyz
```

after
```
[profile configWithProfilePrefix]
AWS_ACCESS_KEY_ID=xyz        
AWS_SECRET_ACCESS_KEY=xyz              
AWS_SESSION_TOKEN=xyz
region = ap-east-1
```

## Problem

Toolkit is using an older Lambda SDK (3.731, latest 3.9xx) due to
compatibility issues. This caused new fields introduced in LMI/DAR to be
not available in local types and need to be manually bypassed. see:
#8392, we need to
update lambda SDK to latest version and resolve all the compatibility
issues

Below is the compatibility issue when trying to upgrade sdk lambda

```

## Reason for Compatibility Error
Upgrading @aws-sdk/client-lambda to version 3.953.0+ (which uses Smithy
v4) causes TypeScript compilation errors due to module path conflicts.
The toolkit's awsClientBuilderV3 uses Smithy v3 types, while the new
Lambda client uses Smithy v4 types. Even though the types are
structurally identical, TypeScript treats them as incompatible because
they're imported from different module paths.

## Solution
Added type assertions (as any and as LambdaSdkClient) in lambdaClient.ts
to bypass TypeScript's type checking when creating the Lambda client.
This allows the new SDK version to work while maintaining runtime
compatibility.

No new tests are required for the lambdaClient.ts changes because there
is no behavior change - The type assertions don't change runtime
behavior, only bypass compile-time type checking. The Lambda client
functions identically before and after.

## Problem

- Users without pre-configured credentials encounter authentication
errors when opening Lambda functions from console
- Credential mismatches between console account and local profile cause
errors even when function is accessible in console:
- `ResourceNotFoundException` when function exists in console account
but not in local profile account
- `AccessDeniedException` when local credentials lack
`lambda:GetFunction` permission but console credentials have access


## Solution
- Add `setupConsoleConnection()` to encapsulate browser-based AWS CLI
`aws login` authentication and use the new connection
- Add `getFunctionWithFallback()` to retrieve Lambda configuration with
automatic console login fallback
- Integrate fallback into `openLambdaFolderForEdit()` to handle missing
credentials and credential mismatches
- Improve error handling to distinguish credential mismatches and
resource access issues
- Handle `ResourceNotFoundException` by showing account-specific error
message before fallback
- Handle `AccessDeniedException` by showing permission error message
before fallback

### Screenshots
#### Show warning message when Lambda GetFunction API returns
ResourceNotFoundException, then automatically proceed with console login
flow

## Background

The Lambda `load-function` URI handler enables a seamless workflow where
users can click "Open in Visual Studio Code" from the AWS Lambda console
to view, edit, and deploy their Lambda functions directly in their
preferred IDE. This feature downloads the function code locally, opens
it in VS Code, and allows users to make changes and deploy updates back
to AWS—all without leaving their development environment.




## Testing

- [X] Tested with no local credentials configured
- [X] Tested credential mismatch scenarios:
- ResourceNotFoundException (function in console account but not local
profile account)
- AccessDeniedException (local credentials lack permission, console
credentials have access)
- [X] Tested user cancellation flow
- [X] Test with SSO connection active

## Problem
- `Amazon Q: Fix all Errors` feature does not work on warning issues.


## Solution

- If user click on `Amazon Q: Fix all Issue` feature from warning issue,
Q should fix both errors and warnings.
- If user click on `Amazon Q: Fix all Issue` feature from error issue, Q
should fix only errors.

Add support for multi-tenant Lambda functions by introducing a Tenant ID
input field in the Local Invoke configuration panel. The field appears
conditionally when the SAM template contains TenancyConfig (either at
function-level or in Globals section).

The tenant ID value is saved in launch.json and passed to SAM CLI when
invoking Lambda functions locally.
