HTTP::Client not running as expected

[finanalyst]

From the documentation

my $client = Cro::HTTP::Client.new(base-uri => "http://foo.com/some/path/");
await $client.get('added'); # http://foo.com/some/path/added

I was expecting the following two sets of code to be the same.
So while this works:

use Cro::HTTP::Client;
my $resp = await Cro::HTTP::Client.get("https://api.github.com/repos/Raku/doc/contents/doc/Language/REPL.rakudoc");
my $json = await $resp.body;
say "json keys are ", $json.keys;

with response

json keys are (content encoding url path type _links sha name html_url download_url size git_url)

This does not

use Cro::HTTP::Client;

my $client = Cro::HTTP::Client.new;
my $resp = await $client.get("https://api.github.com/repos/Raku/doc/contents/doc/Language/REPL.rakudoc");

#my $resp = await Cro::HTTP::Client.get("https://api.github.com/repos/Raku/doc/contents/doc/Language/REPL.rakudoc");
my $json = await $resp.body;
say "json keys are ", $json.keys;

with error message

Cannot keep/break a Promise more than once (status: Broken)

Since the simplest case of an instantiation does not work, I can't use :base-uri, which I would like.

However, in the tests for Cro::HTTP::Client, there is an instantiated object of the class, using :base-uri.

So, what am I doing wrong?

This looks like a flat-out bug. You're not doing anything wrong.

@patrickbkr thanks for the confirmation.
I have just blogged about the journey, and will publish in a couple of days.
Essentially, I called get/push etc on the type variable. It works nicely

@patrickbkr please find blog at https://dev.to/finanalyst/editing-rakudoc-croing-it-to-github-1507
You will see the instance version would be better.
