Description

AnyType is not defined in typescript generated code.
In some situations, schemas return any, this is handled in other languages where that is translated into something the language understands, examples:

• Java: Object
• C#: `Object
• Rust: serde_json:Value

However, this translation is not made for typescript, and the generators write AnyType in such situations, leading to type errors:

Cannot find name 'AnyType'

openapi-generator version

5.0.0-SNAPSHOT

OpenAPI declaration file content or url

The part that is causing troubles look like this:

          "cat": {
            "allOf": [
              {
                "$ref": "#/components/schemas/Cat"
              },
              {
                "description": "Cat information"
              }
            ]

This was generated using @nestjs/swagger and the problem is that the generator is unable to understand the second part and that one ends in _AnyType_

This is a full example:

openapi: 3.0.1

    Adult:
      description: A representation of an adult
      allOf:
      - $ref: '#/components/schemas/Person'
      - type: object
        properties:
          children:
            type: array
            items:
              $ref: "#/components/schemas/Child"
          firstChild:
            allOf:
              - $ref: '#/components/schemas/Person'
              - description: First child
    Child:
      description: A representation of a child
      allOf:
      - type: object
        properties:
          age:
            type: integer
            format: int32
      - $ref: '#/components/schemas/Person'

output using typescript-axios

/**
 * A representation of an adult
 * @export
 * @interface Adult
 */
export interface Adult extends Person {
    /**
     * 
     * @type {Array<Child>}
     * @memberof Adult
     */
    children?: Array<Child>;
    /**
     * 
     * @type {Person & AnyType}
     * @memberof Adult
     */
    firstChild?: Person & AnyType;
}
/**

NOTE: AnyType is not defined anywhere.

Suggest a fix

The proposal is simple, adding a translation for AnyType -> object for all the typescript generators. This can be achieved adding one line to AbstractTypeScriptCodegen.java like the ones we have in other generators:

typeMapping.put("AnyType", "Object");

👍 Thanks for opening this issue!
🏷 I have applied any labels matching special text in your issue.

The team will review the labels and make any necessary changes.

[codeserk]

FYI, I'm working on a fix for this, so I'll present a PR that fixes this situation

[macjohnny]

fixed with #6335

[krajek]

If the fix already present in the published version? I cannot see any versions after 4.3.1, which has the bug.

[codeserk]

@krajek I think it was published only in v5, which I think it's still in beta!

[davidyee]

@krajek @codeserk I ran into the same issue while using the latest stable 4.3.1 but updating to 5.0.0-beta2 resolved the issue. Thanks for the suggestion!

[GunnarAK]

If you're able to; try downgrading to 4.3.0
This resolved the issue for me while I came from 4.1.3. AnyType became Object again.

[Song2017]

openapitools/openapi-generator-cli:v4.2.3 works for me

[wing328]

The latest master has this issue resolved. Please try the SNAPSHOT version (mentioned in the README) and let us know if you've any feedback before the official release of v5.0.0 in Dec 2020.

please can someone explain the fix.i have many problems in openapi like:
-basepath="http://localhost".
-Anytype bug.

Sounds like you probably need to go and ask questions on stack overflow... This is a bug report that has been closed.

Hello!
Not sure what you mean, but the problem that why tried to fix with this patch was related to the present of a symbol called AnyType which was never designed.
I think there were 2 changes involved

• Ensuring any was used for AnyType (the correct symbol in TS).
• Remove any in some situations where it was not needed.

[davija]

@codeserk Sorry, I was trying to reply to the previous post.

[codeserk]

@davija yeah my comment is also an attempt to reply to @Khaled-Slay 😅

[Khaled-Slay]

Thank you for the reply. Every time I generate services with openapi .I get those problemes I manage them by changing Anytype with any.(it seems the generator produces AnyType instead of any) replace the basepath with my basepath .but this gets repetitive. for ModuleWithProvider bug it didn 't stop me from executing my services.

Hello @Khaled-Slay

I'm not sure about the problem with the basepath, but the problem you mention about AnyType was the same problem I found when I created this issue. It should be solved in version 5.x.x, but not in 4.x.x
can you check which version are you using? This problem shouldn't be present in the new version (which I believe it's still in beta phase):

https://hub.docker.com/layers/openapitools/openapi-generator-cli/v5.0.0-beta/images/sha256-fdea7c99b45273354b12e4c84b771af1374a35c69eedbe4fe2cc3da8e9018e0f?context=explore

Hope this helps :)

[Khaled-Slay]

Yap that is it.thank you.much appreaciated

Hello

I am still facing this issue when using the opengenerator version 5.0.0 beta 1-2-3 on the following yaml file : https://github.com/jdegre/5GC_APIs/blob/master/TS29510_Nnrf_NFManagement.yaml (or any) to create python-flask server . Upon running the python -m openapi_server I am greeted with following :

Traceback (most recent call last):

File "C:\Python39\lib\runpy.py", line 197, in _run_module_as_main

return _run_code(code, main_globals, None,

File "C:\Python39\lib\runpy.py", line 87, in _run_code

from openapi_server.models.any_type import AnyType

ModuleNotFoundError: No module named 'openapi_server.models.any_type'

I have tried changing the generator version to 4.3.1 as other thread suggested still nothing and tried all of the beta version but still get this error.

Hello @networkdevCD

Not sure if I'm missing something, but looks like you are using a different generator (python). This change only affected the generator for typescript-axios, but this change had no impact on the generators for python :(

[networkdevCD]

Hello @codeserk

Your correct apologies was get to end of my tether with it and found this bug report . It seems we also have the same issue in the python generator , was there any quick work around you did the with YAML ?

[mpp-doric]

Same deal using the gradle plugin id "org.openapi.generator" version "5.1.0" and generating Kotlin. Manually replacing with kotlins Any does the trick.
