OpenAPI Swagger Import

[Greg Fischer]

I'm having trouble importing an Open Api specification file into Zap using the OpenApi extension.  I keep receiving the error below:

2019-03-19 14:48:06,128 WARN  ExtensionOpenApi - io.swagger.models.properties.StringProperty cannot be cast to io.swagger.models.properties.RefProperty
java.lang.ClassCastException: io.swagger.models.properties.StringProperty cannot be cast to io.swagger.models.properties.RefProperty

I'm importing a OpenApi v2.0 spec directly via the swagger site using the Zap UI.  I downloaded the file and attached an excerpt of it for reference.  Any help would be appreciated.

The error message seems related to type casting error (when you try to convert one value into a class type object). My previous experiences with swagger files is that it sometimes ill formatted. I’d suggest opening your swagger json file in a text editor and verifying if that’s the case. You can manually fix it depending on how bad it looks. I suggest using VSCode and a json beautifier to get it nicely formated for you to review.
