Linode dynamic inventory plugin fails with ip_style=api due to missing ipv6 pools

[ashtarcommunications]

Summary

The linode dynamic inventory plugin fails to parse the inventory when ip_style is set to "api", with an error about a missing attribute instance.ips.ipv6.pools

This appears to be due to line 221:

ips += instance.ips.ipv6.pools

I don't see

It looks like pools was renamed to ranges in linode/linode_api4-python@dc592c7. This was introduced in version 5.4.1: https://github.com/linode/linode_api4-python/releases/tag/v5.4.1

(I really wonder what kind of versioning scheme they use? Breaking changes in a patch version doesn't sound like a good idea to me... Also the PR doesn't mention any kind of motivation for the rename, which doesn't make it any better...)

I created a PR to fix this, could you please test it? #8248

(I have no way to test this.)

I get:
'IPv6Range' object has no attribute 'type'
and the inventory fails to parse

[felixfontein]

Can you paste the full stack trace? Thanks.

I guess in that case further things have changed in a backwards incompatible way. It's probably best if someone who can actually run the plugin against the real service continues debugging and fixing this.
