Description
Experience Level: Entry
I have the following errors on Facebook pixel and I need someone to solve the problem for me as I cant do it myself even though I have included how to fix the problem and 2 of those problems are in two other events so the total is 5.
1- Server Sending Invalid Match Key Parameters for ViewCategory Event
Your server is sending an invalid fbp parameters value for your ViewCategory 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.

How to fix the issue
You'll need to use the solution below to fix the issue.
Once you've fixed the issue in your website code you can mark it as resolved. This will move it to the Previously Detected section. If the issue is found again after 3 days it will move back to the Active section.
Check that you're sending valid and unique values for the fbp parameters for your ViewCategory event and that the data is normalized correctly.
2- AddToCart Event Missing Some Deduplication Parameters
You're sending AddToCart 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 optimization of any ad campaigns that are optimizing for this event.

Add an event_id parameter to all AddToCart events that you're sending from both your pixel and the Conversions API. To add an event_id parameter to the events you're sending through the Conversions API, you can use the Payload Helper tool on the Facebook for Developers site to validate that your payload is set up correctly. To add an event_id parameter to the events you're sending through your pixel, go into your website's source code and add an event_id parameter to each of your AddToCart event instances.
3-Same Event ID Received for Many Event Instances
You're sending the same event ID for many instances of your ViewCategory events. Event IDs are unique identifiers that are used to deduplicate identical events received from your pixel and the Conversions API so they're not counted twice. To ensure Facebook is accurately counting your events, each unique event instance needs its own unique event ID.
This may cause issues with the measurement of your events and the attribution of your ad campaigns.

Update the event_id parameter for your ViewCategory events so that each unique event instance is sending a unique event ID from both your pixel and through the Conversions API. For pixel, you can do this on your website's source code. For Conversions API, you can do this in Graph API Explorer or on your server terminal.
