What is a good explanation for Errors Detected but None are Showing

[ovetteabejuela]

I'm getting this everytime:

But if you go to see what these are, you get this (nothing):

I've read somewhere that it's a data-type problem, but I went to check on them and nothing seems unusual.

Where or what should I look for this?

Thanks in advance!!!

can be anything, you need to identify in which step the error appears, it will have a specific message then, which you can properly solve

[Stachu]

what transformation do you do in the last step then? in the query editor you see all the rows as normal?

Tricky, because I don't show any error in any of the steps.
