Describe the problem/error/question
If I use drag and drop to place a value from a previous node into an expression field, I get invalid expression error. This is specifically in the “Get Sparkline Data” node, where I am trying to use the output value from the “Execute Workflow (Get M2M Token)” node.
What is the error message (if any)?
[ERROR: Invalid expression]
Please share your workflow
