Getting error "TypeError: Cannot read property 'items' of undefined"

[hdi-amiri]

I am using this library with TypeDoc 0.20.26, I get the json output by setting "json": "json-doc" inside my tsconfig.json file and output is generated. But when I want to use it by entering following command to get the yaml output, I get the error that follows:

type2docfx json-doc.json yaml-dir

$ type2docfx json-doc.json .

Same issue here.

Just for better debugging here's a copy of my json which couldn't be parsed (I had to rename to .txt so I could upload on github)

I have the same issue.

Same issue here.

[JordoHeffernan]

Did anyone figure out a fix for this? I'm running into a similar problem.

[XannMagus]

I'm still having the same issue as well

[Gankarloo]

Same issue for me to.

@HadiAmiri could you tell me which version of docfx your use?

[SebHoffmRS]

same problem here.
the isExported flag is missing from the top-level nodes (just like in @iJungleboy 's case file), and I have no idea how to change this.

This is where everything is ignored: https://github.com/docascode/type2docfx/blob/v0.10.5/src/parser.ts#L60

@yunair I use typedoc 0.21.5, type2docfx 0.11.2, and docfx 2.58.0 (btw: why is the docfx version interesting?)

I also don't understand why type2docfx's latest version is 0.11.2 on npmjs.org and the latest version in this repo seems to be 0.10.5.

possibly related: TypeStrong/typedoc#888

As noted in TypeStrong/typedoc#888 ,

The isExported flag was removed in 0.20. TypeDoc only documents exported members now.

See also the release notes https://github.com/TypeStrong/typedoc/releases/tag/v0.20.0 :

isExported / isConstructorProperty ReflectionFlags remvoed

So ignoring nodes without this flag set to true has become incompatible:

Because when you use docfx V2, the corresponding version of type2docfx is 0.10.X.
when you use docfx V3, you need to use a version higher than 0.11.0

[yunair]

The latest version of typedoc that type2docfx support is 0.15
because new version of typedoc change the rule of uid generator, then we can't simply upgrade typedoc.

so if you use docfx V2, you need to install typedoc@0.15.0 and type2docfx@0.10.5.
if you use docfx V3, you need to install typedoc@0.15.0 and type2docfx
