ErrorCode

Type

The codes a MindStudioError carries when a write fails.

The code on a MindStudioError thrown by a write, so you can branch on the failure instead of parsing a message. Both Query and Mutation expose .catch, so you can inspect err.code on a single call, for example treating no_unique_constraint differently from a genuine conflict.
