Error ocurred in mock service: NoMethodError - undefined method `split' for ...

[a-iasevoli]

I'll start by saying that I'm not a Ruby developer and I'm not that familiar with this project.

I have this scenario: 1 pact file with 2 interactions. One interaction has "content-type": "multipart/form-data;boundary=BOUNDARY" in the header The other has "application/json;charset=utf-8" in the header

For some reason, as soon as there is a multipart/form-data between the interactions, pact-support (or mock-service) uses MultipartFormDiffer to get the difference between expected and actual from all the interactions!

If I remove the multipart interaction, MultipartFormDiffer is not used anymore.

Because the body of a application/json;charset=utf-8 request is a json object, split is not defined and it fails.

This is the entire log

Can you fork https://github.com/pact-foundation/pact-ruby-standalone-e2e-example and modify it to recreate the issue please? You don't need to know Ruby.

Sorry it took a bit. Here is the fork https://github.com/ai-dev/pact-ruby-standalone-e2e-example

[bethesque]

Thank you. When it's quick for me to recreate it, it's quick for me to fix it! I've released the fix to the pact-support gem. Are you using one of the wrapper libraries that also needs to be released? (pact-js, python, pact-net?)

[a-iasevoli]

Thanks to you! Yes, I'm using pact-node to create the stub server

[bethesque]

@mboudreau could you release pact-node with 1.67.0 of the standalone when you have a moment please?

[mefellows]

v.8.5.0 on its way out shortly.

Hi Team,

We are getting same issue with pact-net 2.4.6. Is this version of pact-net include this fix. I am trying to create contract file with multipart/form-data Content-Type. Getting Below error from mock service Response Status: 500, Response Body: {"message":"Error ocurred in mock service: NoMethodError - undefined method `split' for #<Array:0x2e2fe28

Is there any example available for creating contract file where we tries to submit form data to Mock service and generates Contract file.

Thanks

@akbhartiya you'll need to supply an executable example so we can recreate the issue. I've submitted a PR to update to the latest ruby standalone here - hopefully that fixes it.

@akbhartiya @bethesque The latest ruby standalone core (1.70.0) will be packaged in Pact-Net 2.4.7, which is building right now.

Thanks Neil. @akbhartiya let us know if you're still having the issue after upgrading.
