Error while checking Approval history

Hi Experts,

Instance: 12.2.5

I entered an invoice in Payables. After validating and create accounting, I initiated the invoice for approval.

When I checked the Invoice approval history through Reports > View Invoice approval history, I am getting the following error

Is it because, there are no approvers defined?

Or is there any other reason for it?

Any help will be highly appreciated

Thanks in advance

Regards,

Pooja
