Hello! We are using jest-pact adapter library for writing our contract tests and want to rewrite one of them to pact-js. But, after updating package

pact-foundation/pact

to version

"^10.1.3"

, - all our tests (that are written on jest-pact library) failed with Axios Network Error and following stack trace. So, even if I want to rewrite one of them on pact-js library, errors never go away. So, tell me please, what is going wrong?

Copy code

Interesting, after a downgrade to 10.1.2, an error seems more informative

It seems like breaking changes that have been on upgrading from version 9.18.1 to 10.0.0 and upper

It seems like that is already a known issue

Thanks for flagging this. I put a note on the issue that points at the problem.

Hey folks sorry I'm late to the party, I'm out at a conference. Looks like there is a bug with the cors options passing and/or core behaviour. We'll dig into this next week when I'm back.
