[BUG] Invoke-PnPBatch : The maximum number of bytes allowed to be read from the stream has been exceeded. After the last read operation, a total of 1064000 bytes has been read from the stream; however a maximum of 1048576 bytes is allowed

Reporting an Issue

I have a SharePoint script inventory that runs some cmdlet like "Set-PnPListItem" and "Add-PnPListItem" with bach parameter.
Then every 50 cmdlets, I run "Invoke-PnPBatch -Batch $batch -Connection $ConnectionSiteInventory"

When executing "Invoke-PnPBatch", randomly I receive the error below :
Le nombre maximum d'octets pouvant être lus à partir du flux a été dépassé. Après la dernière opération de lecture, un total de 1064000 octets a été lu à partir du flux alors qu'un maximum de 1048576 octets est autorisé.

In English I think it's: The maximum number of bytes allowed to be read from the stream has been exceeded. After the last read operation, a total of 1064000 bytes has been read from the stream; however a maximum of 1048576 bytes is allowed

Here is some statistic for 4 complete execution of my script:

• 77 Invoke-PnPBatch, I get 3 errors
• 30 Invoke-PnPBatch, I get 6 errors
• 35 Invoke-PnPBatch, I get 5 errors
• 73 Invoke-PnPBatch, I get 6 errors

Here is the SharePoint item property that I set:

Actual behavior

What is the version of the Cmdlet module you are running?

Which operating system/environment are you running PnP PowerShell on?

• [x ] Windows
• Linux
• MacOS
• Azure Cloud Shell
• Azure Functions
• Other : please specify

Am moving this to discussion since this is specific to your code/script.
Would suggest maybe reducing the number of items to be sent in the batch and then try.

If anyone in the community has a suggestion, would be great to hear from them as well.

Hello,
I change my script to run 1 batch per request...
Now, I don't receive any error between sathurday and sunday, but monday I receive three errors when invoking pnp batch :
The request was canceled due to the configured HttpClient.Timeout of 100 seconds elapsing. (4:00, 4:02, 4:04) maybe network error because same hour...

My first issue is not resolve because I can't run multiple request with PnP Batch. If anyone have same error message when executing PnPBatch with multiple column and value, please keep me informed.
