Error converting value False to type 'AutoRest.Modeler.Model.Schema'

[bernarden]

Since Autorest Core 3.0.6282 was released today, my build is failing to generate c# clients. It was working fine with AutoRest 3.0.6187 and Autorest Core 3.0.6274 just a day ago.

Looks like the same issue as #3497 and #3439 due to additionalProperties: false?

[bernarden]

Yeah. There are additionalProperties: false in my swagger definition but as I mentioned above this became an issue only after @autorest/core 3.0.6282 was released. I fixed my immediate issue by adding --version=3.0.6274 to the list of autorest arguments.

[VaclavK]

tried the switch.. did not work for me I should probably fire separate issue

the underlying spec piece (type with property tied to enum)

  "Customs.Catalog.Domain.Models.Enums.CurrencyIso": {
    "enum": [
      1,
      85
    ],
    "type": "integer",
    "description": "Currency Iso Values",
    "format": "int32"
  },
  "Customs.Catalog.Domain.Models.DTO.RetailerPrice": {
    "type": "object",
    "properties": {
      "amount": {
        "type": "number",
        "description": "Amount",
        "format": "double",
        "nullable": true
      },
      "currency": {
        "allOf": [
          {
            "$ref": "#/components/schemas/Customs.Catalog.Domain.Models.Enums.CurrencyIso"
          }
        ],
        "description": "Currency",
        "nullable": true
      }
    },
    "additionalProperties": false,
    "description": "Price"
  }

From the error message, I think your issue is due to

"currency": {
  "allOf": [
    {
      "$ref": "#/components/schemas/Customs.Catalog.Domain.Models.Enums.CurrencyIso"
    }
  ],
  "description": "Currency",
  "nullable": true
}

Which is not currently supported by Autorest. See Azure/autorest#2652 and Azure/autorest#3417 for workarounds.

[DavidNorena]

same here:

And i think it has nothing to do with the allOf, because I dont have it in my swagger file.

Also experiencing this issue with 3.0.6282.

3.0.6274 is working just fine.

[priyankajayaswal1]

I am using swagger spec 3.0.1 to generate a python client using autorest. I see varied behavior with different versions. Observation:

1. from 6267 - 6277 - FATAL: System.NullReferenceException: Object reference not set to an instance of an object. is coming
2. from 6280 - 6300 - FATAL: Error parsing swagger file. Error converting value False to type 'AutoRest.Modeler.Model.Schema'. Path 'components.schemas.SomeObject.additionalProperties', line 1, position 88165. is coming
3. from 6302 and above it is creating client but without base_url which we need for implementation. 

Can you help us figure out either:

1. How to use the clients generated using azure.core
2. How to fix above issues so that somehow we may create client with base_url support.

To add to this my additionalProperties thing got resolved with 3.0.6274 in csharp but fails like above in python.
