Wait Node not working when Resume parameter is passed as Expression

Questions

Describe the problem/error/question

When I try to pass the Resume parameter to the Wait node as an Expression instead of a Fixed value, a " Problem running workflow" error comes up.

What is the error message (if any)?

The workflow has issues and cannot be executed for that reason. Please fix them first.

Please share your workflow

same,

you could build a workaround with a switch node and multiple wait nodes

Same here, I ended up going this route.

However this should be fixed

Hi @lyfterteam

You can wrap it inside a sub-workflow, then use expressions as you like,

for example this:

      "parameters": {
        "resume": "timeInterval",
        "amount": 5,
        "unit": "seconds",
        "options": {}
      }

could be:

    {
      "parameters": {
        "resume": "{{ $json.Resume }}",
        "amount": {{ $json.seconds }},
        "unit": "seconds",
        "options": {}
      }

In other words, this is like a dynamic workflow that only contains the wait node.

Hey, thanks!

I already solved this in my workflow by using an If statement.

However, its still a bug that needs to be fixed
