Built-in SFTP: Accessing a hash algorithm by manipulating the HashName property is not supported

[maakku]

Describe the Bug

I am trying to upload file content to an SFTP server with the built-in SFTP connector. I get the following error for every file I try to upload:

The service provider action failed with error code 'BadRequest' and error message 'Accessing a hash algorithm by manipulating the HashName property is not supported on this platform. Instead, you must instantiate one of the supplied subtypes (such as HMACSHA1.)'.

The workflow is very basic: it reads files from a SFTP server, loops through the found files, uploads them to another SFTP server inside a for-each loop and deletes the original files.

Plan Type

Standard

Steps to Reproduce the Bug or Issue

1. Try to upload a file to a SFTP server with the built-in connector, uploadFileContent action.

Not sure if this was some temporary glitch, because after running the workflow again in a couple of hours there were no more errors.

[maakku]

This error seems to occur occasionally, could this be an SFTP server issue?

[maakku]

Is the SFTP connector using the SSH.NET library under the hood by any chance?

Could this issue be related to this: sshnet/SSH.NET#859
