PR checklist

• Read the contribution guidelines.
• Pull Request title clearly describes the work in the pull request and Pull Request description provides details about how to validate the work. Missing information here may result in delayed response from the community.
• If contributing template-only or documentation-only changes which will change sample output, build the project beforehand.
• Run the shell script ./bin/generate-samples.shto update all Petstore samples related to your fix. This is important, as CI jobs will verify all generator outputs of your HEAD commit as it would merge with master. These must match the expectations made by your contribution. You may regenerate an individual generator by passing the relevant config(s) as an argument to the script, for example ./bin/generate-samples.sh bin/configs/java*. For Windows users, please run the script in Git BASH.
• File the PR against the correct branch: master, 5.1.x, 6.0.x
• Copy the technical committee to review the pull request if your PR is targeting a particular programming language.

@GORA-SAG thanks for the fix. Can you please merge the latest master into your branch so as to fix the CI failures?

[GORA-SAG]

@wing328 already my branch is merged with the master. Don't know why the CI integration is failing. Can you please have a look on the failure.

[wing328]

Tested locally and works for me. I'll update the doc in another PR.

CI failure not related to this change

Hmm I tried exactly this but it didn't work. Not sure what I did wrong.

[GORA-SAG]

Hi @kuhnroyal , what i did is just changed the separator as (:) for the models as you suggested and changed small thing in the code which is available in the commits.

[kuhnroyal]

@GORA-SAG Yea I saw that and I tested it, I am just not sure why I didn't get it to work a couple days ago when I tried the same thing :)

[GORA-SAG]

@kuhnroyal sometimes that will happen :)
