I'm connecting to input data though an ODBC connection. Screenshot shows a username/password, but I also tried this with a "No Authentication" connection and have the same issue.

Here's my ODBC Connection. Again, I have tried with the Authentication Method of "Not Authentication" as well:

However, when my colleague opens up the same workflow, this is what he sees.

Why would it show that his connection is invalid? I've confirmed that he has same ODBC connection access, it's just that it doesn't seem to connect when he opens up the workflow that I created on my desktop.
