Pact Foundation

:wave::skin-tone-4: all - i'm helping a dev with a failed build relating to a pact test.   nothing seems to have changed on our end but got a `dummy` error message.... i hope it's not us. any ideas in thread

```2022/12/10 00:10:51 [DEBUG] pact setup

```libpact_ffi:
    libname: libpact_ffi
    version: 0.3.15
    hash: e4babe9bd82761f01f595a9fd31a0eb8```

fwiw, it's just an error showing red and doesnt seem to fail the build....  we noticed this along with another test failure which we just cleaned up

also in libpact_ffi-v0.3.14 according to our builds

That is strange. My guess is it's in Pact Go. I'll check tonight

OK because of reasons, all things that can accept a Matcher need to be JSON serialisable. This meant that plain string values got escaped with a `"` so I must have used a dummy matcher a few years back. It seems like it doesn’t cause a functional issues, but I’ve put in a minor fix that essentially detects a string value there and prevents the additional quotes.

It’s in the latest `2.x.x` that has not been released yet (i.e. tagged)

Would you mind seeing if that makes the issue go away?

<@U9UUY3CU9> - looks good now!

I was able to replicate the issue using the prior pact-go 2.x.x version only after updating my local `libpact_ffi` to `0.3.15`.  And ultimately verified your fix on the head of branch 2.x.x.

Thanks for fixing!

correction, it was `v2.0.0-beta.17.0.20221212070231-76032bbaf2b6`  i verified.

Awesome, thank you! I’ll get a new release out in the next couple of days
