Workflow not handling errors like it should

[pyrrho]

Hello @Ecommfox! It sounds like the error handler is designated as a Global Error handler in your workflow and would explain why you cannot connect nodes to it.

For your workflow and the loop block, are you looping over sets of 500 rows or is each workflow run 500 rows only? Would you also mind sharing a screenshot of your loop block setup? We aren't able to access each others workflows via a shared link but I think I have a good understanding of what you are trying to do.

I recently wrote a post about using functions and loop blocks to catch errors in a more meaningful way which might help you derive a solution:

Loop block tells me to refer to {{ value }}, then says it's undefined

Does the loop run even and insert records even though the linter is claiming that value is undefined? Sometimes the linter is tricksy. I notice that you are using the legacy loop block to execute some nested looping (which I have had to do in the past). I recommend trying to shift into the paradigm of creating functions for your workflows which you can then call from a JS setup in the new loop blocks. This way you can gather results from the loop iterations with a try/catch block to format the…
