nil

[IvoWalach]

Hey,
the methods that return hashies kind of dont always work... i tried to get some information from them using the [] method but it sometimes outputs an error "undefined method `[]' for nil:NilClass", so it treats it as nil? im very confused an dont know how to fix that.
Can you help me please?
Thank you

Hey, do you have some example code that can replicate the issue?

I would imagine that some fields are optional in the Discogs API, so when they are not present the value will be a nil and not an instance of a Hashie.

Yeah. Im trying to obtain an artist using an album -
release = wrapper.get_release("123")
Now in order to obtain the artist, i did
release.artists[0].name
(the artist returns a hashie, so i used the [] method to get the first entry and then .name to get the name - everything should be according to the documentation of the hashie class.) But this simply sometimes works, and sometimes doesnt. As i said - it sometimes returns an error as though it was not a hashie class, but a nil class.

Maybe it is something similar to the other issue "Map missing arrays from nil to [] ?"

Thank you very much for your help

I noticed that the console says

[DEPRECATED]: The key 'type_' has been replaced with 'type'. When accessing, please use the latter. This message will be removed in the next major release.
You are setting a key that conflicts with a built-in method Hashie::Mash#type_ defined in Hashie::Mash. This can cause unexpected behavior when accessing the key as a property. You can still access the key via the #[] method.

I guess thats where the problem is, but I dont really understand what it says...
