AI_NoObjectGeneratedError: No object generated: could not parse or validate the response against schema.

What it means
Your app asked the AI model for structured data matching a schema, and the model's answer was cut off mid-sentence or didn't match the required fields.
Likely causes
  • max_completion_tokens was set too low, so the JSON output was truncated before the closing bracket.
  • The output schema has overly complex nested rules without clear field descriptions, or the error wasn't handled as a friendly retry.
Prevention
Set max_completion_tokens to ~2× the longest expected answer and always validate and escape model output before using it.

Copy for your agent

Structured AI output failed with `AI_NoObjectGeneratedError`. Check that `max_completion_tokens` is ~2x the longest expected answer, simplify the schema descriptions, and return a friendly message if validation fails.
