Im trying to Parse a CSV. This is a system that has parsed hundreds of CSVs, but it’s possible the CSV might be quite big now? What is this issue? How do I fix it?
“Maximum call stack size exceeded”
Thank you!

You are already iterating the attachments array, so just use “Data” from the output.
Also, if you read the description below this field, it says to use the toString function, which you haven’t.
If you need further assistance, I think you’ll need to provide a copy of the CSV that’s causing the issue instead… 
Hope this helps! Let me know if there are any further questions or issues.

Hello @Kayla_Tannenbaum 
Thank you very much for reporting this. We sincerely apologise for the inconvenience caused. We have already reported this issue to our development team. I’ll update you as soon as I have any news. Or you can also submit a ticket to be the first to know any updates.
Thank you very much for your patience. 
We also face the same issue since 28.08.2025 and need fast resolution. The production environment is affected. The toString function is enabled.
This Scenario was running for years without any issues or changes.
I’m having the same issue and it’s surprising because we had the process working for years. 2 days ago it started giving this error (this process and another one that is pretty similar).
Anything changed? We didn’t change the size in our files. My file is not a binary.
