Increase http get bufer?

Posted on by DrFahrdahin

Hi guys,

i've made a flow that's downloading some file via http get to onedive.
It works fine for small files but with one file i'm hitting (what seems to be) a buffer limit.

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

104857600 translates to 100 Megs which makes sense.

I'm wondering if this is a hard limit or if there's an workaround to increase the buffer?

Cheers,

Rob

Hi @DrFahrdahin,

Could you please share a screenshot of your flow's configuration?

There is a limit in message size of a single outgoing request, the max message size is 100 MB and not all APIs support the full 100 MB. I afraid that there is no way to increase the buffer in Microsoft Flow currently.

More details about the limits for a single outgoing request, please check the following article:

Request Limits

Best regards,

Kris

Is there any way around this yet? Chunking, etc? This makes it impossible to download large binary files such as videos using Flow.

@Anonymous If the server supports partial content requests, then you can simply add a HTTP range header like:
Range: bytes=0-104857599
https://docs.microsoft.com/de-de/azure/logic-apps/logic-apps-handle-large-messages

Works fine for me, except getting the GET header details doesn't.

I'll try to use this path, but I'm not sure how to use my token within the header. Because it is manage by my custom connector.

I'll test some actions.

Thanks !

Running into the same issue. Getting a file that is approx 138MB over HTTP, but it's failing due to the same error. Works fine when less than 100MB. Anyone find a solution yet for this (beyond manually chunking the request up?)
