Bug: `pull request simple` field `head.repo` schema incorrect

[tisonkun]

g = ... # obtain the client
prs = g.paginate(g.rest.pulls.list, owner='apache', repo='pulsar', state='open')
pr = next(prs)

gives:

It looks like the head field in response can be none but the type annotation indicate it must not be none.

[tisonkun]

Workaround now by passing map_func=lambda x: x.json()

[yanyongyu]

it seems like there is an error in gh rest api definition or codegen. I will take a look at your example.

[yanyongyu]

by the way, which client auth strategy you are using? i think the missing of repo field may caused by the permission of github app. github app can not get any repo info (include fork repos) if the app is not installed on it and the repo field will be none

[tisonkun]

FYI GitHub(TokenAuthStrategy(<Your-Personal-Token>)).

cc @yanyongyu I'd like to know whether you can reproduce the case now.

[yanyongyu]

yes, i can reproduce the error. the repo field missing is caused by the deletion of pr head repo (example apache/pulsar#6036)

[yanyongyu]

In the gh schema, the repo field of pull request head object is "$ref": "#/components/schemas/repository" and cannot be nullable. we may need to patch the schema and report the issue to github/rest-api-description

[yanyongyu]

i have created an issue github/rest-api-description#1811 related to this and make a patch to githubkit until the schema is corrected.

[tisonkun]

Cool! Yes, I think we should patch downstream here...the challenge may be preventing codegen from accidental regression (that is, you may some fix, but the codegen revert it, lol). Or if you can oversee all the commits, a manual fix can work for now.

UPDATED: It seems [tool.codegen.schema-overrides] works well. That's awesome >_<
