So I created a resource and two text boxes that interpolate the values into the URL:
/mailbox/namespaces/{{ Namespace.text }}/messages/{{ MessageId.text }}
However when I run it, it says it fails, and clicking on the Debug button that pops up says “Oops! Something went wrong” and asks me to retry… which of course just does the same thing again.
Where is the API pane that shows the eval? I see in the log pane it says:
11:10:24 [GetMessageById]Datasource structure could not be retrieved GetMessageById.datasource
