No error log available for background tasks?

I'm currently trying to run a background task, that has to go through 20k iterations and on every iteration, pull api data and add this info to a database. For some weird reason it just always end in an error: unable to locate 'variable'.

So I wanted to look trough the error logs, but they don't seem to exist?? it only gives a short message about the error?

Does Xano have any other logging functionality? And if not, could I add this myself using some sort of 3rd party?
