#19778 Errors when running check command with the pyright typecheck backend Issue created by olivercoleman-switchdin Describe the bug This is possibly two separate issues, can separate if need be. I'm getting errors when trying to run

check

with the pyright typecheck backend. The first error I came across was:

$ pants check ::
01:36:53.39 [INFO] Initializing scheduler...
01:36:56.76 [INFO] Scheduler initialized.
01:36:56.89 [WARN] DEPRECATED: Not explicitly providing [python-infer].use_rust_parser is scheduled to be removed in version 2.18.0.dev0.

Read the help for [python-infer].use_rust_parser <https://www.pantsbuild.org/v2.17/docs/reference-python-infer#use_rust_parser>, then set the value in pants.toml.

KeyError: 'pyright'

Then I happened to put

[tool.pyright]

in the pyproject.toml file (and nothing more), and got a different error:

$ pants check ::
