error: SyntaxError: '=>' expected as a result of empty oneOfs

[deannashih]

Hi! Looks like any field with an empty oneOf is causing the script to error out with a syntax error:
error: SyntaxError: '=>' expected

In my specific case, it's

SyntaxError: '=>' expected. (237:16)
  235 |
  236 | };
> 237 | "MetaQuote": ();

In the input file, MetaQuote is defined as:

MetaQuote:
      oneOf: []
      discriminator:
        propertyName: meta_serialization_key
        mapping: {}

Only after I removed all fields with an empty oneOf did the script stop erroring out.

It may be similar to #561, where the fix was made for empty enums.

Start working on it.
So what's the expected result of oneOf: [] and allOf: []?
Is it undefined, @deannashih?

Also it's can be any or unknown, but I prefer undefined for stronger typing.

Got this result:

UPD: #830

@drwpow @sadfsdfdsa Looks like this issue re-emerged in v5.2.0. Was working in 5.1.0.

I believe this was fixed in #1069 for version 6. Previously, this schema generated like so:

MetaQuote: ;

but now generates as:

MetaQuote: never;

Comment here if different behavior is desired.
