Uncaught FormatException: SyntaxError: Unexpected token 'U', "Unauthorized" is not valid JSON

[Dalois-30]

Hello,
I encountered an issue when trying to authenticate using the admin API key. The application throws an Uncaught FormatException with the message "SyntaxError: Unexpected token 'U', "Unauthorized" is not valid JSON". This happens when the API response is not in JSON format but a plain text error message.

Error Stack Trace:
main.dart.js:3818 Uncaught FormatException: SyntaxError: Unexpected token 'U', "Unauthorized" is not valid JSON
