fix: Handle api key error

[goudbor]

Breaks the task loop on ANY error by propagating error up the stack and returning to caller from coroutine. The generic message "Error during task loop" is printed to chat.

Resolves #483

@rbren I can check specifically for api key errors and only raise on that condition?

[rbren]
