Execution List will not show flow - shows an orange spinner on it

Describe the problem/error/question

When I try to open workflow execution details, the executions list shows them as “succeeded,” but the details panel just spins forever. I don’t see the JSON output of the run.

If I copy the execution back into the editor, I can see what it did — so the execution data is stored in Postgres, but the execution viewer in the UI fails to load it.
