The Zeebe ThrowError RPC supports passing variables (used as arbitrary metadata and available from the BPMN process instance) along with the error. This is available in the current Zeebe release 8.6 and earlier releases back to at least 8.3:

• Camunda 8 Docs / 8.6 / APIs / Zeebe API (gRPC) / Zeebe API RPCs / ThrowError RPC
• Camunda 8 Docs / 8.3 / APIs / Zeebe API (gRPC) / ThrowError RPC

Currently the Dapr Zeebe Command Binding (as of 1.14) does not accept variables:

https://docs.dapr.io/reference/components-reference/supported-bindings/zeebe-command/#throw-error

This is a proposal to add support for passing variables as optional data for the binding alongside the existing jobKey, errorCode and errorMessage. If provided, the value of variables will be sent to the ThrowError command of the Zeebe client.
