Size limits are checked when you submit, and a request over one is rejected with 413 and a code naming the limit. A request over a rate or concurrency limit is rejected with 429 rate_limited and a Retry-After header giving the seconds to wait.

One limit cannot be checked in advance: the document and the Questionnaire are read together, and if they are too large to process together the job fails with input_too_large. Split the document or the Questionnaire and submit the parts as separate jobs.
