[New-bugs-announce] [issue45269] c_make_encoder() has uncovered error: "argument 1 must be dict or None"

[Nikita Sobolev]

New submission from Nikita Sobolev <mail at sobolevn.me>:

Looks like we never test error that `markers` are limited to `None` and `dict` types. Here: https://github.com/python/cpython/blob/main/Modules/_json.c#L1252-L1255

Coverage report: https://app.codecov.io/gh/python/cpython/blob/master/Modules/_json.c line: 1252

I will submit a unit test for it today.
