Append Fields: The Target Stream was not properly initialized

[Sarath27]

Hi All,

Workflow in Alteryx designer runs successfully and output also generated in respective folder. But same workflow throws an error as "• The Target stream was not properly initialized. (ToolId: 239)".

What is the resolution for this? Tried multiple times to resolve this, but the issue still persist. 

And also I am getting "Both left and right must have input connections", but Alteryx desktop works well, the error is only with Alteryx Sandbox server.

Please assist me in this issues, stuck at this for almost a month.

Thanks in Advance.

Check your connections on the Server side. What sort of workflow did you upload? Can you share a sample here?

One of your datastreams has 0 records on Server or is part of a disabled container. This is usually beacuse a file is missing or cannot be accessed from the server.
