The process ID to be already filled out.

Error message

The process ID to be already filled out.

What it means

When converting a DAP Attach request to protobuf, the process ID field is asserted to already be filled out; an attach request without a PID cannot be serialized, indicating an upstream debug configuration that never resolved its process ID.

Solutions

1. Validate attach requests carry a process ID before conversion
2. Resolve the PID earlier in debug scenario setup
3. Send an Option/absent PID instead of asserting
