Solutions

1. Address the cause reported by the error message: Unsupported vector: the reported value
2. Verify the inputs, configuration values, and classpath/dependency setup related to this operation, then retry.

Example fix

Correct the condition described ("Unsupported vector: the reported value") and rerun the job or command.

When it happens

Trigger: Triggered at runtime when the operation fails because: Unsupported vector: the reported value.

Common situations: Commonly caused by misconfiguration, missing dependencies or files, unsupported types or operations, or invalid user input leading to: Unsupported vector: the reported value.
