I'm seeing the exact same issue calling the exact same api starting on July 19. I can no longer fetch my daily sales data. I've had this call automated for a few years now and it generally works as expected until this.
This seems to be an issue effecting multiple customers, not an individual user issue.
Request:
GET https://api.appstoreconnect.apple.com/v1/salesReports?filter[frequency]=DAILY&filter[reportSubType]=SUMMARY&filter[reportType]=SALES&filter[vendorNumber]=********&filter[reportDate]=2024-07-18
Error message:
{
"errors": [{
"status": "500",
"code": "UNEXPECTED_ERROR",
"title": "An unexpected error occurred.",
"detail": "An unexpected error occurred on the server side. If this issue continues, contact us at https://developer.apple.com/contact/."
}]
}
