Is there a reason why my deployed workflow fails with 'Cannot read property '$return_value' of undefined' but works when tested with the same trigger data?

Any reason why I get a Cannot read property ‘$return_value’ of undefined on my deployed workflow but when I test the workflow using the exact same trigger data I have no errors and it works perfectly??

Hi , may I confirm if you faced the Cannot read property '$return_value' of undefined error on the Builder UI (image below for example) right?

It only happens when the workflow is deployed. I do not get it when I text on any nodes

Could you share more detail about your workflow? A screenshot will help alot
