Invoices are getting failed while importing only for one specific supplier.

Summary:

All invoices from one specific supplier are failing to import, but no issues are arising when keying them manually. There seems to be some issue with the image that is blocking it from being imported. Is there any specific configuration or format needed in order to get the issue resolved? May I know the reason of this issue? I am trying to check this issue internally, but there is no issue while importing it manually, so i am not able to detect the root cause.
