OPERATION_NOT_SUPPORTED

Property	Value
HTTP status	501 Not Implemented
Retryable	Yes
Error code	OPERATION_NOT_SUPPORTED

Summary

The requested operation is not implemented or supported by this connector or service version.

When it occurs

• Calling an endpoint that exists in the API specification but has not been implemented by the connector.
• Requesting a capability (e.g., key revocation, online certificate status) that the underlying technology does not support.
• Using a feature that requires a higher interface version than the connector implements.
• Invoking an operation on a connector that does not advertise the corresponding interface in its GET /v2/info response.

How to fix

• Check the connector's info endpoint (GET /v2/connectors/{uuid}/info) to see which interfaces and feature flags it supports.
• Use an alternative approach or workflow supported by the connector.
• If the operation is essential, consider using a different connector implementation that supports it.
