Describe the problem/error/question
I have created a workflow, and it worked fine. But one time I ran the workflow and it returned this error: Problem Running Workflow: The expression evaluated to a falsy value: a.ok(to). After that, I cannot run any node in the workflow and they always returned the same error. When I refresh the page and ran the workflow again, it worked. But when I run the workflow the second time, it still returned that error
Please share your workflow
(Select the nodes on your canvas and use the keyboard shortcuts CMD+C/CTRL+C and CMD+V/CTRL+V to copy and paste the workflow.)
