invalid_primary_output
What happened
An indicator that declares more than one output must say which one is the signal, with primary, and it must be one of the declared outputs. Which one is the signal is never guessed, so a spec without one is refused.
What to do
Tell the chat which output is the main signal, or give the indicator a single output.
Example
text
