    It sounds like you’re facing an issue related to interpreting the JSON data and the redirection of data between GTM Server-Side and GA4. Please note some nuances about the Measurement Protocol: it uses the POST method to collect data, thus sending information within the body of the request. However, in your case, it seems like data is not being passed within a POST request body but is rather seen as a URL parameter in a GET request.

    Regarding the redirection to ‘https://www.google-analytics.com/g/collect’ instead of ‘www.google-analytics.com/mp/collect’, it seems there is a misconfiguration since it should be going to ‘/mp/collect’, which is the endpoint for the Measurement Protocol.

    The issue could be rooted in an error in your GTM Server configuration or a mistake in the Measurement Protocol parameters. I would suggest checking your server-side tagging setup in GTM to ensure that it’s set to handle POST requests and validate your Measurement Protocol parameters.
