Incorrect 400 response when downloading subscriber report

I am attempting to download subscriber reports for my app. I'm using the following URL with vendorNumber redacted: https://api.appstoreconnect.apple.com/v1/salesReports?filter[frequency]=DAILY&filter[reportSubType]=DETAILED&filter[reportType]=SUBSCRIBER&filter[reportDate]=2024-04-04&filter[vendorNumber]=xxxxxxxx&filter[version]=1_3

I am getting the following response:

            "id": "92183ac5-7881-436c-ac66-5d89673c5070",
            "status": "400",
            "code": "PARAMETER_ERROR.INVALID",
            "title": "A parameter has an invalid value",
            "detail": "Invalid vendor number specified. Try again.",
            "source": {
                "parameter": "filter[vendorNumber]"
            }

However when I use the same vendor number for the sales summary report: https://api.appstoreconnect.apple.com/v1/salesReports?filter[frequency]=MONTHLY&filter[reportDate]=2023-09&filter[reportSubType]=SUMMARY&filter[reportType]=SALES&filter[vendorNumber]=xxxxxxxx&filter[version]=1_0

I get a proper response. I believe I should be getting a 404 on this response, but am not. This issue can be tracked back to 2019, can we please get some detail about this response?
