Good morning community
I am having an issue when uploading data from a SFTP server. I previously configured the connection account to the server: user, password, host, etc.
When I start the data adding process, I select the CSV file from which I want to extract the information and the delimited file format, in this case using semicolon, I get the following error message:
"Preview Error
Network error: Unexpected token 'u', "upstream r"... is not valid JSON".
As shown in the following screenshot:

I thought the problem was related to the whole instance or environment. However, I did a test with a test SFTP server and everything works correctly. Likewise, I created another connection account with the same credentials and I get the same error message.
Thank you very much in advance.
