Error message

(error as Error).message || error

What it means

Not a thrown error: in DevServer's pre-aggregation code conversion endpoint, CubeSchemaConverter.generate() failures (schema parse/compile errors in the submitted pre-aggregation code) are caught and returned as HTTP 400 with the error message instead of crashing the dev server.

Solutions

1. Review the returned message — it describes the schema compilation problem in the converted pre-aggregation code.
2. Check that the pre-aggregation definition (measures, dimensions, timeDimension, granularity) references existing cube members.
3. Fix the pre-aggregation code in the data model and retry the conversion.
