Redactable: TypeAlias = str | V1EnvVar | dict[Any, Any] | tuple[Any, ...] | list[Any]
@cache
def _get_v1_env_var_type() -> type:
try:
from kubernetes.client import V1EnvVar
except ImportError:
return type("V1EnvVar", (), {})
return V1EnvVar
def _is_v1_env_var(v: Any) -> TypeGuard[V1EnvVar]:

This passes on current master and bisects to the merge commit of #19183.
@ilevkivskyi could you please take a look? I feel like that PR only fixed this issue accidentally and does not resolve the root cause, but would love to be proven wrong!
hauntsaninja commentedon Jul 10, 2025
Is probably same as this comment: #19183 (comment)
ilevkivskyi commentedon Jul 10, 2025
Yeah, that is a valid fix for this case. No need to keep this open.
