Code block runs 4 times instead of 3 and 4. run seems to fail

[Zoker]

Describe the issue/error/question

My goal is build a update notification workflow.
I get the version from a online json file, compare it to the current version and then notify based on the result. When I run the workflow, I get an error in the “Prepare ha-version.json” file. For some reason I get 4 runs there and the 4. seems to fail.

What is the error message (if any)?

Hey @Zoker,

I am not sure why that is running 4 times, Do you have a screenshot of the flow itself showing the data items going into the node?

The only thing I can think of is that for some reason one of the nodes before it is executing twice.

[Zoker]

Do you mean something like this?

Or what data do you want to see?

Thanks for the quick reply

[Jon]

Hey @Zoker,

More the workflow itself, I know you pasted it but a screenshot of the workflow with all the counts on it could be useful.

[Zoker]

Ah sure, here you go:

Well all of that looks fine to me, I am not sure what is going on there. I will have a play in the morning and see if I can find anything.
