Scenario:
Within Logic App constructing a string variable - sendtosftp
Using this data creating a new file on the SFTP server.
If the constructed variable size exceeds 50 MB size limit, get an error similar to:
{
"status": 400,
"message": "The provided file size '58100000' for the create or update operation exceeded the maximum allowed file size '52428800' using non-chunked transfer mode. Please enable chunked transfer mode to create or update large files.\r\nclientRequestId: xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx",
"error": {
"message": "The provided file size '58100000' for the create or update operation exceeded the maximum allowed file size '52428800' using non-chunked transfer mode. Please enable chunked transfer mode to create or update large files."
},
"source": "sftpwithssh-eus.azconn-eus.p.azurewebsites.net"
}
This issue happens even though "Allow Chunking" property is set to "On".
Resolution:
Before sending the data to SFTP, create a Compose action and set its value to the previous string variable.
Add the "body" to the Compose action.
e.g.
"Compose": {
"inputs": {
"body": "@variables('sendtosftp')"
},
"runAfter": {
"Until": [
"Succeeded"
]
},
"type": "Compose"
},
"Create_file": {
"inputs": {
"body": "@body('Compose')",
