Anybody ever had this error? I am not including a custom template in my app.

More above it also gives the error:
otree.templating.errors.TemplateRenderingError: Error while rendering the 'fld' tag: ValueError: not enough values to unpack (expected 2, got 1) (line 11, in "fld")

For me this error was caused because I had a typo in "choices" in the player class.
