Power Automate Large File Error with On Premise Gateway

(0) ShareShare
ReportReport
Posted on by Microsoft Employee

I have designed a Flow that communicates to On Premise REST API developed in .NET via On Premise Gateway. It sends Base64String of a document from SharePoint and expects modified Base64String which then is updated to some other external system via API. 

 

This is working fine with smaller files, but I have a large file around 17 MB. When I am sending this to Custom Connector connected using gateway, I am getting following error.... 

 

Gateway on endpoint '<ii>sb://wabi-us-north-central-b-relay23.servicebus.windows.net/28583ca4-dbec-47a5-b010-10892b4ad503/</ii>' is unreachable.
