Binary field data type is not yet supported

Error message

Binary field data type is not yet supported

What it means

Raised by the WireFieldDataType-to-InfluxFieldType conversion in the catalog's line-protocol/record parser when a field is declared with the reserved Binary wire type; InfluxFieldType has no binary representation, so the write cannot be typed.

Solutions

1. Re-send the data using a supported field type (string, integer, unsigned, float, boolean)
2. Encode binary payloads as base64 strings if binary-like data must be stored
3. Check whether the client library is emitting the reserved binary type unintentionally

When it happens

Trigger: Thrown at influxdb3_catalog/src/format/records/table.rs:291 when the library encounters an invalid state.

Common situations: See trigger scenarios.
