Different report results between Google Analytics 4 UI and Google Data API data

I have a list of customers set in GA4 and I am using the google API analytics for GA4 to retrieve daily the traffic metrics for reporting purposes.

Checking the metrics day by day, I noticed a lot of differences in the metrics between the GA UI web and the answer given by google API.

I thought that there was an error in the logic of my pipeline but I obtained the SAME VALUES, testing THE SAME REQUEST by runReport from the official google guide
using:

• property id
• JSON request body:

{
 "dimensions": [
   {
     "name": "date"
   },
   {
     "name": "deviceCategory"
   },
   {
     "name": "hostName"
   },
   {
     "name": "pagePathPlusQueryString"
   },
   {
     "name": "pageTitle"
   },
   {
     "name": "sessionDefaultChannelGrouping"
   }
 ],
 "metrics": [
   {
     "name": "engagedSessions"
   },
   {
     "name": "newUsers"
   },
   {
     "name": "screenPageViews"
   },
   {
     "name": "sessions"
   },
   {
     "name": "userEngagementDuration"
   }
 ],
 "dateRanges": [
   {
     "startDate": "yesterday",
     "endDate": "yesterday"
   }
 ],
 "metricAggregations": [
   "TOTAL"
 ]
}

After some tests, I realized that I retrieve higher and wrong values ONLY when I use in the API RunReportRequest the dimensions "PagePathPlusQueryString" and/or "pagePath" and/or "pageTitle".

The only way that allows me to obtain the perfect match between GA API and Google Analytics Web UI is by removing these values.

I didn’t see any limitations or best practices about the dimensions above need to be included in a request, so I don’t understand where the error is and why I get the wrong values.

Please, can you help me?
