Resolved Simple import got stalled

We have a python script that executes in a cloud server that uploads the csv file to our site server and then, calls the frontend import of CSVI.

Sometimes, it works fine and performs the import, but it sometimes doesn't work and the import process gets "stalled". When executed through the web browser for the very same csv file, it works perfectly.

Attached you may find the log of an automatic import stalled (1126) and the log of an import triggered from my browser (1125).

In both cases the CSV file to import is the same and they happened with minutes of difference.

We have been dealing with this for 2 weeks and it's driving me crazy. Can you please help?

We are in RO CSVI 7.20 and in PHP 8.0.28.

Thanks!!
