Reported 2021-07-28 14:04:13 PDT
Created attachment 434463 [details] issue with firing an attribution request I'm currently doing end-to-end testing for integration with PCM. However, I'm stuck in the last step "fire an attribution request.". Currently I'm facing two issues and wonder how could I resolve them. [Private Click Measurement] Received error: 'MIME Type is not a JSON MIME type' for ad click attribution request. [Private Click Measurement] Received error: '' for ad click attribution request. Looks like errors are from https://github.com/WebKit/WebKit/blob/d25c25a5db1f4c1c822e4b382544d123b828a15f/Source/WebKit/NetworkProcess/PrivateClickMeasurementManager.cpp#L369-L371 Thanks.

Hi! Does the eTLD+1 of your endpoint have a valid TLS certificate?

Hi John, thanks for quick reply. The report is supposed to send to "https://www.pinterest.com/.well-known/attribution-reporting/report-attribution/" and we believe "www.pinterest.com" should have valid TLS cert.

The report path should be "https://www.pinterest.com/.well-known/private-click-measurement/report-attribution/". Sorry for the typo.

Got a different error message. [Private Click Measurement] Received error: 'The request timed out.' for ad click attribution request. After changing to response MIME type to "application/json", still having the same error message: [Log] [Private Click Measurement] About to fire an attribution request. [Error] [Private Click Measurement] Received error: 'MIME Type is not a JSON MIME type' for ad click attribution request. [Log] [Private Click Measurement] About to fire an attribution request. [Error] [Private Click Measurement] Received error: '' for ad click attribution request.

(In reply to Maojie from comment #3) > The report path should be > "https://www.pinterest.com/.well-known/private-click-measurement/report- > attribution/". Sorry for the typo. PCM sends reports to the eTLD+1, in your case https://pinterest.com/.well-known/private-click-measurement/report-attribution/ without "www.".
