Undefined method `=~' for [:ReturnEnvelope, :Boolean]:Array

[acimadamore]

I'm receiving the error in the title when sending a Letter. It seems that the problem is with attributes that are mapped to Open API type that is an Ruby Array.

In this error in particular return_envelope is mapped to Array[:ReturnEnvelope, :Boolean]:

lob-ruby/lib/openapi_client/models/letter.rb

Line 190 in 2591d23

:'return_envelope' => Array[:'ReturnEnvelope', :'Boolean'],

The second if in Letter#build_from_hash breaks because a =~ is sent to the array instance:

lob-ruby/lib/openapi_client/models/letter.rb

Line 624 in 2591d23

elsif type =~ /\AArray<(.*)>/i

Maybe the third if should precede the second one and add a check if type responds_to(:=~)? This problem should be present in all the implementations of build_form_hash of other model classes.

Thanks!

Hey, I hit this issue too: #216, see their reply there.

I'm hitting this same issue with gem version 6.0.9 after upgrading to Ruby 3.2.0. Is Lob doing anything about this? Am I expected to patch the code myself and rebuild the gem?

That's a shame, I was hoping the newer versions fixed it.
You can use my fork over here. I haven't updated it to the latest, it's on 6.0.5.

@arich Thanks. I ended up forking it as well and patching it with your code suggestion. That fixed the issue. I will hold out hope that Lob figures this out so I can use the official gem.

Sounds good, I'm not promising I'll maintain this forever so best to use your own fork!
