}Could you please try this one. |

Seems to me it's due to the following: Is that expected - an array of array of Object ? Null pointer exception is gone after removing the nested array (replaced with just and "Object" (model) is not defined, is that supposed to have at least one property ? How do you obtain the Swagger Spec ? |
|
Thanks for looking into this, don't know why scalatra generated that swagger spec with Object in it. Anyways, after changing my model, I noticed I am getting the same error with: "geo_area":{
"position":2,
"type":"array",
"items":{
"type":"array",
"items":{
"type":"number"
}
}
} |

@sundriver can you please given an an example of what |
|
FWIW, the output @sundriver presented is Swagger 1.2, where there was no support for nested arrays. The conversion to 2.0 may fail on that or produce something unexpected which would lead to the failure experienced. |

Hi Could you please help how this exception is resolved? Would like to know the corrrect schema declaration for this ? I am using swagger2.0 related issue raised by me |

The swagger-parser now has fallbacks for malformed types. Please give master a try. |
Hi Swagger-Codegen team,
I just updated my local copy to the latest version, 2.1.2 and I am receiving the following error:

I don't know if it matters or not, I am using Scalatra 2.4, Scala 2.11.6.
I appreciate your advise,
Ali
