Starting from 2025-08-07, our backoffice system always got 400 error when calling /v1/financeReports. In previous months, we can get the report successfully with no issue. Here is one dump with some header hidden,
The response looked very strange, it is not a json response but a HTML dump.
The request URI is like following:
?filter[regionCode]=US&filter[reportDate]=2025-10&filter[reportType]=FINANCE_DETAIL&filter[vendorNumber]=XXXXXX
I used the key to generate JWT, and use postman to access the endpoints, I couldn't get the prevous month reports any more.
based on the http status code and response, it is quite clueless which parameter caused issue.
Anyone encountered similiar issue, really appreciated for the help.
