Hi masters,

I’m beginner in odoo , need advice and solution

I installed 3rd party app, when I click ‘export xls ‘ button and gave me the below error.

OS : Ubuntu Server 22.04. LTS
Odoo ver : 16 CE

RPC_ERROR

Odoo Server Error

Traceback (most recent call last):
  File "/opt/odoo16/odoo16/custom/inventory_report_generator/controllers/main.py", line 48, in get_report_xlsx
    report_obj.get_inventory_xlsx_report(options, response,
  File "/opt/odoo16/odoo16/custom/inventory_report_generator/models/inventory_report.py", line 283, in get_inventory_xlsx_report
    for rec in report_data_main[0]:
IndexError: list index out of range

The above server error caused the following client error:
