How to overcome the 100mb buffer file size error

Question

I made a Power Automate that copies a file from a SharePoint document library to an Azure Blob storage.

This works fine, until I hit a file bigger than 100mb. Then I get this message:

"Http request failed as there is an error: 'Cannot write more bytes to the buffer than the configured maximum buffer size: 104857600.'."

Some actions allow to turn on chunking in their settings, but this is not one of those. I've tried using a REST call action to get the file content, but the same error pops up.

Is there any way around this issue? And if not, what is a good alternative, or best practice?

Answer 1

It's unfortunate that there is no way could increase the maximum buffer size, it has reached the limits of message size 100MB (104857600bytes = 100 MB).

You could refer to this document:

Maybe you can use the power shell to copy a file from a SharePoint document library to an Azure Blob storage. Here is the link: SharePoint Documents Libraries copy into Azure Blob Storage
