“Changes” endpoint errors out with `Cannot resolve caller INTERPOLATE`

[AlexDaniel]

Not sure if it's a regression in Cro or Rakudo itself, but:

⚠ test Cannot resolve caller INTERPOLATE(Match:D: Str:D, BOOTInt, BOOTInt, BOOTInt, BOOTInt, VMNull); none of these signatures match:

It happens here: https://github.com/kensanata/oddmuse6/blob/a82b7ea9f1b7046238d0856f4477e23baf0e6495/lib/Oddmuse/Routes.pm6#L42-L44

I changed it to:

 get -> 'view', $id where $changes { 

And it started to work!

[kensanata]

I get no errors...

[AlexDaniel]

What's your rakudo and cro versions?

EDIT: OK, from another ticket:

This is Rakudo Star version 2018.10 built on MoarVM version 2018.10 implementing Perl 6.c.

I think you should try with newer rakudo…

[kensanata]

I just ran all the tests on moar-2020-07 and didn't get any errors any more. Can we close this issue, @AlexDaniel?

[AlexDaniel]

Yeah, I guess so!
