The match type NEGATIVE_BROAD is not valid for this specific op.
You tried to apply the match type ‘NEGATIVE_BROAD’ during a targeting creation event where that specific match type is structurally disallowed (e.g., trying to use EXACT targeting inside an Auto group, or applying a negative match type to a positive targeting endpoint).
Double-check the specific endpoint you are targeting. Ensure the matchType field matches the exact permitted enum string for the context you are building (Broad, Phrase, or Exact).
