testsuite fails on alpine linux

[ncopa]

I suspect some of the dependencies was updated and introduces a regression, but I don't know which or how to fix this.

Thanks, @ncopa! I'm not all too familiar with Alpine. If I wanted to add a GitHub workflow that tested this on Alpine using Docker images, what would be the easiest way for me to replicate the above?

[oalders]

Am adding workflows in #104. That may help find the issue.

[oalders]

Looks like this is not specific to Alpine at all.

[oalders]

Seems to be here: https://metacpan.org/source/OALDERS/WWW-Mechanize-Cached-1.53/lib/WWW/Mechanize/Cached.pm#L193

It's expecting the header to be an arrayref and it chokes when there's a scalar.

[ncopa]

So the problem is in WWW-Mechanize-Cached and should be fixed there?

[oalders]

Yes. I may get a fix in there today.

@ncopa Tested successfully against MetaCPAN-Client-2.026000 on Alpine linux

Still has an issue with HTTP::Tiny: but the test succeeds so it appears to be expected

[oalders]

Thanks @timlegge. I have opened this issue with HTTP::Tiny: chansen/p5-http-tiny#137. I can fix it on this end as well.

So, I need to release a new WWW::Mechanize::Cached and then fix the undef warning here, bump the version of WWW::Mechanize::Cached and then release a new MetaCPAN::Client. :)

[oalders]

I've uploaded a new MetaCPAN::Client to CPAN. Let me know if you still have any issues. Thanks @ncopa and @timlegge!
