Closed stephenchu closed 5 years ago

Using:

$ nr version

Got this when I run:

$ nr get users
panic: reflect: call of reflect.Value.Interface on zero Value

Hi @stephenchu

Thanks for your request. It seems that the problem caused by the output printed. The default output format is as TABLE. My testing data is OK in output TABLE format, maybe your data is more complex than mine.

Can you please try to append -o json argument to output as JSON format to narrow down the problem scope if it caused by printer? Like: nr get users -o json

Thanks! Chan Gao

Interesting: You're right. I was able to do both nr get users -o {json,yaml} just fine.

stephenchu commented 5 years ago

I do see from the stack trace that it is trying to reference a path of /Users/gaochan/Documents/zwork/software/Golang, which I obviously don't have. Could that be the issue?

@stephenchu

Thanks for your testing so much. I will do further debugging for this.

Thanks! Chan Gao
