pb33f/libopenapi does not support nullable attribute

[h6ah4i]

Hi. I noticed an issue that blocks me to use runn v0.100 or newer. Recent versions of runn use pb33f/libopenapi-validator for validating API requests and responses. The library has an issue that does not support nullable property. Unfortunately, the author of libopenapi gave up to support them due to relying its validation feature is depends on third-party library...

ref.) pb33f/libopenapi#265 nullable: true for response validation

@h6ah4i Thank you for your report!

In v0.103.2, nullable attributes for request and response are now supported.

Try it out if you like 👍

Thank you for the rapid response!

However, the workaround introduced in v0.103.2 did not helped me in my setup unfortunately. It seems the current workaround only support very basic syntax of OpenAPI, so it did not work for schema files using [allOf] (and maybe oneOf and anyOf) syntax(es).

Could you take a look at the following code that I have added some test cases into the http validator test.go.

In v0.103.3, I fixed it to pass the test you added. Thank you!

@k1LoW Thank you so much! It seems like the validation failure caused by the nullable attribute has been gone for me in v0.103.3.

Still, I get many OpenAPI validation errors in v0.100.0+, so I have reported two new issues.

• OpenAPI validation fails for range of response codes (4XX, 5XX, ...) #881
• OpenAPI validation fails on Multiple methods defined on the same path #882
