Ruby 3 upgrade throws kernel error for the overwritten each method

[kajatiger]

🐞 Bug Report

Steps to reproduce

We have an item that is the first hyperlink to the actual media and need to iterate through the sub nodes of it:

item.sub_nodes.map(&:name).to_s

And then we get an error saying

SystemStackError:
        stack level too deep

since upgrading the rails app to ruby 3 (and rails 6.1)

Expected behavior

We would expect to get a string back that contains the name of each item sub node.

Possible Solution

We don't exactly have a solution, but suppose the answer would be somewhere in the definition of the each block here:

hyperclient/lib/hyperclient/link.rb

Line 28 in 0e445dc

def each(&block)

[dblock]

Start by adding Ruby 3 to https://github.com/codegram/hyperclient/blob/master/.travis.yml, do we have a repro of this out of the box with existing specs? If not, try building a repro?

We fixed this in one spot now with adding embedded:

Looks like impulse is a private repo @kajatiger.

I fixed CI/CD with GHA on this repo and added Ruby 3.2 without issues. Interested in taking this on @kajatiger?
