    Variable ATTR_ERROR_MESSAGEConst Experimental

    ATTR_ERROR_MESSAGE: "error.message" = ...

    A message providing more detail about an error in human-readable form.

    Unexpected input type: string
    
    The user has exceeded their storage quota
    

    error.message should provide additional context and detail about an error. It is NOT RECOMMENDED to duplicate the value of error.type in error.message. It is also NOT RECOMMENDED to duplicate the value of exception.message in error.message.

    error.message is NOT RECOMMENDED for metrics or spans due to its unbounded cardinality and overlap with span status.

    This attribute is experimental and is subject to breaking changes in minor releases of @opentelemetry/semantic-conventions.

    Use domain-specific error message attribute. For example, use feature_flag.error.message for feature flag errors.
