Expected behaviour

Using VSCode test running shortcuts gives in the same results as using the terminal eg. go test when running a provider pact.VerifyProvider() test.

Actual behaviour

Because VSCode env has VERBOSE_LOGGING=XXX the pact-provider-verifier binary outputs lines like

I, [2020-10-29T17:19:51.954432 #51162]  INFO -- request: POST http://localhost:53219/__setup
D, [2020-10-29T17:19:51.954501 #51162] DEBUG -- request: User-Agent: "Faraday v0.17.3"
Content-Type: "application/json"

This results in the verification raising a JSON unmarshalling error: error verifying provider: invalid character 'c' looking for beginning of value

Steps to reproduce

Set VERBOSE_LOGGING="" in your test env and the unmarshal will error.

Sorry I thought I'd triaged this. Thanks for the report, we may need to exclude that env var to avoid interference.

A workaround would be to create a workspace setting to exclude that from passing into the go runtime when you run via the IDE.

I'm having this error too. Could you elaborate on how to work around this error?

EDIT: unset VERBOSE_LOGGING

Closing as unplanned, as the 2.x.x release won't have this issue.
