Reused schemas only use default data type value in first occurance

[mhpkmd]

It seems like when your openapi spec is reusing the same schema in multiple endpoints (or when referring to the same schema from other schemas), portman does only generate default data type values on the first occurrence (i.e. a integer type -65321). On all following occurrences the field of same type seems to be treated as a string (i.e. same integer type would be "" as raw body.
This happens on all properties where example field is not defined.

Very simple openapi taken from Swaggers Pet shop examples and scaled down:

Imported collections in POSTMAN looks like this:

First occurrence

Second occurrence

Expected result
I was expected that portman would generate default data type values on all properties where examples are not defined, on every occurrence of a schema.

hi @mhpkmd

That looks like unwanted behavior.
We will have to run some validations to see where this behavior is originating.

[thim81]

hi @mhpkmd

We just converted the provided OpenAPI file without any special configuration and it was always using the provided examples:

Could it be that you are using an older version of Portman?

[mhpkmd]

Hi @thim81

The issue persist in my end.

Took the same data as in the INPUT field of the original post, inserted it into a new file (openapi3_0-input.json). Ran the command below and the issue with types in the PUT endpoint persist.

Command
portman init -l .\openapi\openapi3_0-input.json -o .\output\openapi3_0-output.postman_collection.example.json -s .\config\postman-config.example.default.json

Running portman v1.26.5 (portman --verison) which seems to be the newest

Also, please notice that the issue reported in visible in the output text even before importing it into Postman like highlighted in the picture below:

[thim81]

hi @mhpkmd

Your command uses a custom Postman config (postman-config.example.default.json)
portman init -l .\openapi\openapi3_0-input.json -o .\output\openapi3_0-output.postman_collection.example.json -s .\config\postman-config.example.default.json

What is the content of the postman-config.example.default.json?

Can you try to do the conversion without the -s .\config\postman-config.example.default.json?

There is a Postman configuration parameter exampleParametersResolution that influences how the request body is rendered: using the example values OR the schema (aka integer, string, ...).

@thim81
The output is the same when I run the following command (without option):
portman init -l .\openapi\openapi3_0-input.json -o .\output\openapi3_0-output.postman_collection.example.json

The option file looks like this:
{ "folderStrategy": "Tags", "requestParametersResolution": "Example", "exampleParametersResolution": "Schema", "keepImplicitHeaders": true, "enableOptionalParameters": false }

Actually I just realized that when I don't set option explicit, portman is using default (portman-config.default.json). No such file exist in my root directory so I am a little in doubt of what options file it is actually using in this case.

[thim81]

hi @mhpkmd

Can you try to modify your Postman config file to use "exampleParametersResolution": "Example":

{
  "folderStrategy": "Tags",
  "requestParametersResolution": "Example",
  "exampleParametersResolution": "Example",
  "keepImplicitHeaders": true,
  "enableOptionalParameters": false
}

This will influence which values will be used when creating the request in Postman (details):

Select whether to generate the response parameters based on the schema or the example in the schema.

[mhpkmd]

hi @thim81

Forget my previous comment (now deleted). It actually seems to work with these settings. I'll run some tests in a larger scale to either confirm or deny if this actually fixed it.

[thim81]

After your testing, if it is working as expected, feel free to close the issue.
If you run into issues, let us know.

[mhpkmd]

I havn't been able to reproduce the issue after these settings, even though I was sure that I already tried that setup. Closing the issue, and thanks for the clarification.
