[DX]: show error when invalid credentials

[revolunet]

Looks like the app crash when given invalid mainKey/userId. maybe we should show a specific error message

devtools also dont show up in that case

[franky47]

Looks like this is non-base64 characters in the mainKey, which is a temporary intermediary solution to authenticate clients. It could be fixed by using a Zod parser to validate the mainKey string format before attempting to decode it.

Fixed in 6099b68

(This issue also arise when signup/login from the SDK)

[franky47]

It should not, since the SDK accepts a Uint8Array for the main key, so it's up to the calling code to provide a correct key. This will be abstracted by authentication strategies.

We could however check the main key length beforehand.
