Hello there, I've been continuing on with my Pactflow proof of concept. However I started running into an issue yesterday where the

AVJ

processing has been throwing the error:

"message": "discriminator: mapping is not supported"

. It seems to me like something has changed on the Pactflow side? For example if I reupload the latest working version of my OAS spec, Pactflow processes it correctly. It looks like it's loading the comparison from cache as it shows:

Comparison details
Compared at
2025-08-18 11:57:19 GMT+1
Verifier
pactflow-openapi-pact-comparator
Version
1.5.1

Then, if I simply change the version attribute in the OAS and no changes whatsoever to the rest of the OAS, I get the error

info:
   version: {bump this}

I can also see that the comparison details show a brand new comparison:

1.6.0

The key difference seems to be that version 1.6.0 throws the error on identical yaml contents

hmm strange, we recently added support for

mapping

(in this PR)

I will share a sample OAS with you directly via direct message
