I have been looking at some posts here, none with a concrete solution.
Here my problem:
I installed OnPremise Data Gateway to search an SQL database. Within PowerApps I am able to connect to the database, I am able to read this data, but I am not able to load this data into a CDS entity. The table has 105k rows.
I have hit my face on the wall in the error: "code":"0x80072322","message":"Number of requests exceeded the limit of 6000 over time window of 300 seconds."
We limit the number of API requests made by each user, per organization instance, within a five minute sliding window. Additionally, we limit the number of concurrent requests that may come in at one time. When one of these limits is exceeded, an exception will be thrown by the platform.
So I think the problem that you met is because of this limit.
I think maybe you need to read this doc about api limit in PowerApps:
