Retryable: `no`.\n\n## DESCRIPTION\n\nRaised by `POST /api/entity/stats/{entityName}/{modelVersion}/query`. The supported operators are `sum`, `avg`, `min`, `max` and `stdev`, spelled lowercase. Anything else — including `count`, an uppercase spelling, or a typo — is rejected, and the message echoes the value that was sent.\n\nThere is no `count` operator because every bucket already carries `count`. `stdev` is the sample standard deviation (divisor `n − 1`) and is `null` when a bucket has fewer than two numeric samples.\n\n## SEE ALSO\n\n- errors\n- crud\n- errors.INVALID_AGGREGATION_FIELD\n- errors.DUPLICATE_AGGREGATION_ALIAS\n",
