Google Search does not work in agents

[Phlasse]

What happened?

Hi there, I am using the agents endpoint and configured it like this:
agents:
allowedProviders:
- customendpoint
disableBuilder: false

I set the env vars for the google search:
GOOGLE_SEARCH_API_KEY: "ccc"
GOOGLE_CSE_ID: "ddd"

Chatting and even dalle works like a charm since 0.7.8 is released, but the web search api simply returns:
Error processing tool: Request failed with status 400: Request contains an invalid argument.

Maybe I am missing a crucial point here, but it worked with plugins in earlier versions, but now it does not.
I am using azure/openai endpoints in the customendpoint via litellm. Works usually.

Version Information

0.7.8

Steps to Reproduce

agents:
allowedProviders:
- customendpoint
disableBuilder: false

I set the env vars for the google search:
GOOGLE_SEARCH_API_KEY: "ccc"
GOOGLE_CSE_ID: "ddd"

What browsers are you seeing the problem on?

Chrome

Relevant log output

Error processing tool: Request failed with status 400: Request contains an invalid argument.

You need to provide logs from the backend to fully understand the issue.

Log locations:

• Docker: Project root directory ./logs
• npm: ./api/logs

There are two types of logs that can help diagnose the issue:

• debug logs (debug-YYYY-MM-DD.log)
• error logs (error-YYYY-MM-DD.log)

Error logs contain exact stack traces and are especially helpful, but both can provide valuable information.

Please only include the relevant portions of logs that correspond to when you reproduced the error.

Thanks for the hint of where I can find logs. I will provide a little later!
