Hey folks, I'm experiencing some problems with pact provider verification via the new ``contract_requiring_verification_published`` webhook. My pact broker is hosted on sh1989.pactflow.io The error I receive is:

pact_1 | bundler: failed to load command: /pact/bin/pact (/pact/bin/pact)

pact_1 | /usr/lib/ruby/gems/3.0.0/gems/pact-1.63.0/lib/pact/hal/entity.rb53in `_link!': Could not find relation 'pb:latest-provider-pacts' in resource at https://sh1989.pactflow.io/pacts/provider/pact-provider/consumer/pact-consumer/pact-version/70a8e3b23699154f9342895ea8bac8e8d79396e3/metadata/Y3ZuPWRmMTgwMmI2Jnc9dHJ1ZQ (PacthalRelationNotFoundError)

This is what comes back from `GET /pacts/provider/pact-provider/consumer/pact-consumer/pact-version/70a8e3b23699154f9342895ea8bac8e8d79396e3/metadata/Y3ZuPWRmMTgwMmI2Jnc9dHJ1ZQ`:

Can you please share the full verbose output?

You base URL is wrong.

Beth (pactflow.io/Pact Broker/pact-ruby)

12/15/2022, 2:40 AM

It should be

Copy code

--pact-broker-base-url <https://sh1989.pactflow.io>

Beth (pactflow.io/Pact Broker/pact-ruby)

12/15/2022, 2:40 AM

that’s an unusual combination of attributes

Beth (pactflow.io/Pact Broker/pact-ruby)

12/15/2022, 2:41 AM

you either want to set your

--pact-broker-base-url

and

--provider

OR you set the pact URL.

Beth (pactflow.io/Pact Broker/pact-ruby)

12/15/2022, 2:41 AM

you shouldn’t be setting both.

Beth (pactflow.io/Pact Broker/pact-ruby)

12/15/2022, 2:42 AM

when you do a verification, either you’re verifying a changed pact at a specific URL, passed in via the webhook (so, just provide the pact URL parameter) OR you’re doing a verification of all the provider’s pacts because the provider has changed (in which case, you set the base URL and the provider name)

Thanks Beth! If I run the first option, I get the error:

No value provided for required option '--provider'

But once I added that back in too it worked correctly 🙂 and glad it was something simple! I was also a bit confused by the documentation here https://docs.pact.io/provider/recommended_configuration, which says that "When the pact URL is known, the

pactBrokerUrl

providerName

consumerVersionSelectors/consumerVersionTags

enablePending

includeWipPactsSince

fields should not be set" - but maybe that's specific to the JS/Ruby libs rather than via the CLI

Beth (pactflow.io/Pact Broker/pact-ruby)

12/15/2022, 10:13 PM

No, same recommendation @Sam Hogarth

Beth (pactflow.io/Pact Broker/pact-ruby)

12/15/2022, 10:13 PM

it’s the same underlying code.

Beth (pactflow.io/Pact Broker/pact-ruby)

12/15/2022, 10:14 PM

Can you send me the exact command and error stack for when you saw

No value provided for required option '--provider'

Beth (pactflow.io/Pact Broker/pact-ruby)

12/15/2022, 10:14 PM

because that error doens’t seem right.

Beth (pactflow.io/Pact Broker/pact-ruby)

12/15/2022, 10:15 PM

and the version of the CLI

Sam Hogarth

12/16/2022, 11:46 AM

Of course, gimme a few hours

Running

pactfoundation/pact-cli

docker container with digest

sha256:e0a783b0

(v0.51.0), here's the output from my terminal:

> --broker-token fake-token \
> --verbose true
No value provided for required option '--provider'

Sadly there's no deeper error stack than that. Simply adding the extra arg (

--provider pact-provider

- sorry about the poor provider name there 😓) makes that command work successfully.

Beth (pactflow.io/Pact Broker/pact-ruby)

01/24/2023, 3:12 AM

@Sam Hogarth it’s because you gave it a pact broker base url.

Beth (pactflow.io/Pact Broker/pact-ruby)

01/24/2023, 3:12 AM

Take that out.

Beth (pactflow.io/Pact Broker/pact-ruby)

01/24/2023, 3:12 AM

You either give it a pact URL, OR you give it a base URL and a provider name.

Beth (pactflow.io/Pact Broker/pact-ruby)

01/24/2023, 3:12 AM

Don’t do both.
