Problem stopping execution Cannot read properties of undefined (reading 'cancel')

[LinkedUp_Online]

Describe the problem/error/question

I often get workflows that get stuck, and can’t be canceled. If I press the stop button in this exucution overview, I get an error. See below.

What is the error message (if any)?

“Problem stopping execution
Cannot read properties of undefined (reading ‘cancel’)”

What is going wrong and how can I stop this behavior?

Hi @LinkedUp_Online Can you try updating to the latest version? Looking at this thread, it looks like we’ve put out a few fixes recently that should handle this:

ERROR: Cannot read properties of undefined (reading 'name')

Thanks a lot @craSH for sharing the stacktrace. That’s all that we needed to fix this . Here is a PR that addresses this. It’ll likely be released in 1.34.0 on Wednesday.

Another user who was still encountering this had this resolved by updating to 1.38.0, so updating should be your first port of call here!

Had a similar problem and upgrading to 1.38 fixed it.
