Panic error when executing example code

[smorz]

Hi!
When executing the example code, I came across the following error, which, as far as I understood, is related to the field header of the wallet object in the Invoice function in the lnpay.go file.

$ go run lnpay-test.go
panic: runtime error: invalid memory address or nil pointer dereference
[signal SIGSEGV: segmentation violation code=0x1 addr=0x0 pc=0x6c36cc]

goroutine 1 [running]:

That's because we didn't handle the error from CreateWallet on the example (so the example wasn't bloated). You must always handle the error there in real code. It will probably say that you used an invalid API Key or something like that.

Sorry for the confusion.

Thank you.
I checked the error from CreateWallet and it was nil, And I tested with a real sak then even the wallet was created in the dashboard. But that error is still occurring.
I put a fmt.Println(wal.header) after line 67 of lnpay.go (err = resp.ToJSON(&wal)) and resulted in the panic error in that line.
May it mean that lnpay has a problem with my IP, and doesn't answer correctly to that?
Or does the version of go matter? It's 1.15

At this point I would think this library is broken then. But it was tested before and I didn't see this error ocurring ever, so that's very weird.
