Server Sending Invalid Match Key Parameters for PageView Event

Hi there,

In recent weeks we’ve started to see the below two warnings on our Facebook Pixel on Facebook Business Manager.

In the past couple of weeks I have enabled Conversion API as recommend. Prior to that only the pixel was active.

Are these errors actually issues, or just false positives caused by both the pixel and the conversions API sending data back to Facebook now?

“Server Sending Invalid Match Key Parameters for PageView Event
Your server is sending an invalid fn, phone parameters value for your PageView event. This may be because there was an error in the parameter value.
This may cause issues with the attribution and delivery optimization of ad campaigns that are using this event.”

“GeneralEvent Event missing some deduplication parameters
You’re sending GeneralEvent events through both your pixel and the Conversions API, but they’re not being deduplicated properly because not enough of these events are receiving an event_id parameter. Event instances sent without an event_id parameter cannot be deduplicated.
This may cause issues with the measurement of your events as well as the attribution and delivery optimisation of any ad campaigns that are optimising for this event.”
