EDIT: Ahhh, I see what’s the issue… Knime does not allow you to pass flow variables as password:
“Attempt to overwrite the password with config key 'password' failed. It's not possible to overwrite passwords with flow variables.”
In that case, the workaround would be to use the Credentials object instead. You can do it like this:
Just add a Variable to Credentials node, and configured like this:
And in the GET Request, just use the Credentials option, and choose the Credentials object you set in the Variable to Credentials node like this:
@LoicCR I’ll take a wild guess and suggest to put your flow variables in quotes*. I had a similar problem in the past, but with the DB Query Reader:
I tried to use Flow Variables to parameterise my SQL statements in the DB Query Reader Node. It worked hardcoded, but not with Flow Variables. Turned out more quotes were needed because of how the values are injected. This looks awfully similar, might be the issue.
