Hi all,

I am running into an issue when inserting rows into an Excel file.

I am using the M365 connector 'Send and HTTP request' to POST the rows into an Excel.

The rows are in a JSON format.

The flow works fine if the JSON contains less than 20,000 rows of data. But as my dataset contains 25,000 rows, the flow is throwing a 'Redirect' message with code 302, which is not really an error.

So instead of troubleshooting the error below, I was thinking of finding a solution to the redirect error knowing that the flow works perfectly with less than 20k rows.

    "message": "The response is not in a JSON format.",
    "innerError": "Cannot read server response."
 
Any idea how I can handle this please?
 
Below is my Flow. We are getting the JSON from Powerapps and I am creating the Excel file on Onedrive.

This is what I receive when it is returning the redirect

"Location": "/error/error.html?aspxerrorpath=/x/_layouts/xlrestinternal.aspx",

but in case of success the location is https://graph.microsoft.com/
