Data Import Through Bench Keeps Failing

Frappe Framework Bug
1

I found that the data import through bench keeps failing, it seems it is a bug of the frappe data-import.

bench --site site2.local data-import --file /home/erpadmin/frappe-bench/sites/site2.local/private/files/20260111itemr4.csv --doctype "Item" --type insert

It seems that this is the issue:

  • payload_count is supposed to be set when the Data Import record is created.

  • In CLI imports (bench data-import), sometimes the Data Import document isn’t fully initialized, leaving payload_count as None.

  • That makes the comparison invalid (int < NoneType).

I cannot import through bench suddenly after latest update
