Cannot convert type null with $ref #26
Description
I am trying to convert a json schema that should either be null or a $ref to another object. In this case the reference is just a simple string but this could be arbitrarily complicated.
The design of the json schema follows the advice given here:
Input
{ "anyOf": [ { "$ref": "#/my_object" }, { "type": "null" } ], "my_object": { "type": "string" } }I expected the output to be somewhat similar to this:
Expected Output
{ "nullable": true, "$ref": "#/my_object", "my_object": { "type": "string" } }However, it actually caused the package to crash:
Error
Error at Object.<anonymous> ([...]/json-schema-to-openapi-schema/index.js:8:30) at Module._compile (internal/modules/cjs/loader.js:1158:30) at Object.Module._extensions..js (internal/modules/cjs/loader.js:1178:10) at Module.load (internal/modules/cjs/loader.js:1002:32) at Function.Module._load (internal/modules/cjs/loader.js:901:14) at Module.require (internal/modules/cjs/loader.js:1044:19) at require (internal/modules/cjs/helpers.js:77:18) at Object.<anonymous> ([...]/json-schema-to-openapi/index.js:3:19) at Module._compile (internal/modules/cjs/loader.js:1158:30) at Object.Module._extensions..js (internal/modules/cjs/loader.js:1178:10) { name: 'InvalidTypeError', message: 'Type "null" is not a valid type' }I believe this issue is similar to #21. However, in that case you could easily adjust the json schema using the "type": [] syntax. Here it is different. I guess the only alternative would be to make all referenced objects nullable, which I would like to avoid.
I believe this would be a great addition for converting rather complicated schemata. :)
