What happened?

It seems that menuinst-1-1-2.schema.json needs to be added to schemas.conda.org.

Using

conda_build.post._check_one_menuinst_json("menu.json")

Results in

WARNING: Could not fetch 'https://schemas.conda.org/menuinst-1-1-2.schema.json', status code 404
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "/usr/local/Caskroom/miniforge/base/lib/python3.12/site-packages/conda_build/post.py", line 1760, in _check_one_menuinst_json
    raise RuntimeError(f"Could not build validator for schema '{schema_url}'.")
RuntimeError: Could not build validator for schema 'https://schemas.conda.org/menuinst-1-1-2.schema.json'.

This occurs when building a conda package from feedstock.

It seems that this validation failure did not raise an exception prior to conda 25.11, but now does.

It seems that this validation failure did not raise an exception prior to conda 25.11, but now does.

Yep, this was added in conda/conda-build#5828
