Hi there! Encountered an error with lily (calibrationnet) and walk job. When the job tries to process block 435326 lily daemon restarts with the following in the logs:

panic: reflect: call of reflect.Value.NumField on zero Value [recovered]
        panic: reflect: call of reflect.Value.NumField on zero Value [recovered]
        panic: reflect: call of reflect.Value.NumField on zero Value

If I skip that particular block, everything goes well

I suspect the fix in #890 will also address this
