Command line tool : TypeError: Cannot read property 'call' of undefined

[milanbr]

When run:

api-spec-converter pisp.apib --from=api_blueprint --to=swagger_2 > swagger.json

I get:

Can you share your apibp file? The command works for me with this one:

https://raw.githubusercontent.com/apiaryio/api-blueprint/master/examples/Polls%20API.md

[mieszkomalawski]

Same here, when converting from openapi_3 to swagger_2

[canvural]

Same happens to me. From api_blueprint to openapi_3

[rbren]

If anyone can share a file that triggers this bug, I'm happy to try and reproduce.

[mieszkomalawski]

Unfortunately I cannot share because definition contains company internal APIs, maybe @milanbr or @canvural can?

The error occurs in api-spec-converter/node_modules/composite-error/lib/compositeError.js on line 45. I've added console.log(this.originalStackDescriptor); to check what's happening:

api-spec-converter tries to call .get on this object, but there is no get-key.

Edit: api_blueprint to openapi_3.

Edit: :arrow_right: We used integer instead of number in some cases. This caused the parser error. :arrow_left:

[rbren]

Thanks for the details!

Unfortunately I wasn't able to trigger the error by setting a query parameter to integer - any more details you can share on how to reproduce?

I had the same problem and added another line in bluebirds promise.js (line 658) to track the problem down:

console.log(JSON.stringify(reason, null, 4));

This is the error message I got:

{
    "name": "CompositeError",
    "message": "Failed to parse spec",
    "innerErrors": [
        {
            "result": {
                "_version": "2.2",
                "error": {
                    "code": 2,
                    "message": "the use of carriage return(s) '\\r' in source data isn't currently supported, please contact makers",
                    "location": [
                        {
                            "index": 1087,
                            "length": 1
                        }
                    ]
                },
                "warnings": []
            }
        }
    ],

After a change all line-endings to LF (unix) the converter worked

[peterhut]

Encountered the same issue trying to convert the apibp file downloaded from https://gost1.docs.apiary.io/ Attached: gost1.apib.txt

[blazekv]

I had same problem as @gunters63 . File was saved with CRLF. Saving file as Unix style solves the problem.

@rbren IMHO It will be sufficient to handle error message and raise more specific message. Original error message is really confusing.
