GET Request Authentication Credential Weirdness

Hi there,

I’ve been struggling to use some sort of credentials input in my workflow to work with the GET Request node to retrieve data via an API from our internal system (so I can share the workflow with colleagues without giving my credentials away to everybody to see).

My plan was to use the Credentials Input node to store my credentials (semi?) safe in a variable and insert them in the GET Request node authentication. If I manually insert my credentials in the GET node with the Digest authentication method, all seems to be working perfectly, however it did not work at all with the credentials variable. Luckily the 4.0 version of the GET node allowed for a NTLM (Labs) authentication method, which seems to be working perfectly and according to my plan… however…

In my test with 13 working API queries with the manual credentials input, I noticed one query was constantly returning an empty body (but did have a status 200). The only difference between the queries are the dates and the query is working fine when using it in Python.

Any ideas what is going on?

Also why would manual credentials input work, but not with the credentials input node?
