Describe the issue you are experiencing

for some reason the automation trace (of seemingly only this automation?) is not displayed correctly. I suspect some issue while parsing the json of the tracefile... it seems to cut off the first letter of the "action" list after the first couple entries and it continues for the rest of the trace. Given that the automation affected does not seem that complex it kinda surprises me.

Describe the behavior you expected

correct rendering of the trace graph and timeline

Steps to reproduce the issue

Afaik this issue has existed since I created the automation ~December 2023

Consider to change condition: null into condition: [] in your automation. That will render the graph and may solve the other issues as well.

thank you, I was using the UI to build most of the automation, I would have guessed it only produces valid flows ;)
