[yoshihirok]

I want to use over 1MB file in File System service with On-Premises data gateway.

and want to use the File contect in below actions.

My scenario:

scenario 1: Upload the File to specific OneDrive for Business.

Message mean "Failed HTTP request, because Timeout."

@DavidBurg How create file limit is 20MB my flow fails on create file/file system connector if file is more than 2 MB, IS i'M MISSING SOME THING? flows runs perfectly fine if file is less than 2MB

The support for files over 2 MB is done via chunking. Follow the steps to handle message chunking with connectors documented here:

https://docs.microsoft.com/en-us/azure/logic-apps/logic-apps-handle-large-messages#chunked-message-h...

@daviburg just one thing How I can add chunked parameter in Create file/File System connector.

Peek code of my Connector is;

{
    "inputs": {
        "host": {
            "connection": {
                "name": "@parameters('$connections')['shared_filesystem_1']['connectionId']"
            }
        },
        "method": "post",
        "body": "@outputs('Compose_3')",
        "headers": {
            "ReadFileMetadataFromServer": true
        },
        "path": "/datasets/default/files",
        "queries": {
            "folderPath": "\\Daily Activity\\Automated Reports\\ABS Reports",
            "name": "@items('Apply_to_each')?['Name']",
            "queryParametersSingleEncoded": true
        },
        "authentication": "@parameters('$authentication')"
    },
    "limit": {
        "timeout": "P1D"
    },
    "metadata": {
        "flowSystemMetadata": {
            "swaggerOperationId": "CreateFile"
        }
    }
}

So how can I edit connector's JSON?

[daviburg]

My understanding is that the connector will attempt chunking if the input allows it. So you do not have a parameter to set to explicitly enable it. This in my opinion is why the documentation explain how to use chunking compatible inputs.

@daviburg I don't know where I'm lagging. My file is just 3.1 MB and unable to download it in local server. Every time flows fails with file create of just 2MB. Now I'm as per documentation store content in variable and than pass this variable to compose action,, after this I pass output of compose action to file content of create file action.

Harry, could you open a support ticket with us Microsoft so a customer support engineer may troubleshoot the issue with you and ensure success?

This is known limitation and I have confirmed with Microsoft Support - Reference - https://docs.microsoft.com/en-us/data-integration/gateway/service-gateway-onprem#considerations 

Please upvote the idea, so that Microsoft can remove this limitation  - https://powerusers.microsoft.com/t5/Power-Automate-Ideas/Remove-2MB-limit-of-Service-Gateway/idi-p/9...

The linked limitation is regarding a single message via the gateway. The point of chunking is to break down the request in multiple messages to go beyond the size limit of a single message. There was likely a confusion as to the inquiry.

When is this change happening? 2017 and seeing it still is 50mb...

I have CSVs being added to the folder at 50+mb and the flow doesnt run at all unless its sub 50mb...
