So I know that there are tons of responses out there on this error but I am not finding the response I need or the fix I need so I am going to post this up under my specific situation.
I have a flow that goes against Dataverse and the idea is to pull and SSRS report, push it to a PDF, and then email said PDF. I found the steps here and they look legit: https://reenhanced.com/2021/download-dynamics-365-reports-as-a-pdf-with-power-automate/
So here is my problem. At the point of this process where I am downloading the PDF via the created URL is when I get the JSON error that I see here:
{
"error": {
"code": 302,
"source": "flow-apim-unitedstates-002-eastus-01.azure-apim.net",
"clientRequestId": "f55c3bc9-ad66-46fa-9e19-834533fd4668",
"message": "The response is not in a JSON format.",
"innerError": "<html><head><title>Object moved</title></head><body>\r\n<h2>Object moved to <a href=\"/_common/error/err.aspx?BackUri=&ErrorCode=0x80048287&Parm0=%0d%0a%0d%0a&RequestUri=%2fReserved.ReportViewerWebControl.axd%3fReportSession%3dxjjfwhifrwnz5d55nbsn1szz%26Culture%3d1033%26CultureOverrides%3dTrue%26UICulture%3d1033%26UICultureOverrides%3dTrue%26ReportStack%3d1%26ControlID%3d1914e4cf91924830ad0d0b63b1580b31%26RSProxy%3dhttps%253a%252f%252fbn1700srs.nam.reporting.cds.dynamics.com%252freportserver%26OpType%3dExport%26FileName%3dMASB%2bInvoice%26ContentDisposition%3dAlwaysAttachment%26Format%3dPDF%26rc%3aPrintOnOpen%3dtrue&user_lcid=1033\">here</a>.</h2>\r\n</body></html>\r\n"
}
}
My flow looks like this in the area of pulling that URL:
Looking at the failure, this is what I am seeing:
The URL that is being used in the GET request: /Reserved.ReportViewerWebControl.axd?ReportSession=xjjfwhifrwnz5d55nbsn1szz&Culture=1033&CultureOverrides=True&UICulture=1033&UICultureOverrides=True&ReportStack=1&ControlID=1914e4cf91924830ad0d0b63b1580b31&RSProxy=https%3a%2f%2fbn1700srs.nam.reporting.cds.dynamics.com%2freportserver&OpType=Export&FileName=MASB+Invoice&ContentDisposition=AlwaysAttachment&Format=PDF&rc:PrintOnOpen=true
I have attempted to use Headers in the HTTP GET request of Accept: */* and Accept: application/json. I have tried with both there and with each on their own.
What am I missing or what simple step is missing in this?
Thanks.
Jayson
