isErrorFromPath seems to be inferring a never type

The Bug

Here is a reproduction CodeSandbox.

I am using openapi-zod-client to generate a zodios api, and am trying to use isErrorFromPath to narrow error types. However, I seem to get a never type when attempting to use it (see screenshot).

Workaround

You can work around this by adding an alias and using isErrorFromAlias instead. But this is quite a chore since we are generating the zodios api from an openapi yaml file. Regenerating the zodios api will also result in losing these alias fields.

Thank you for the report and the reproductible exemple.

This should be fixed in version v10.7.7 : https://codesandbox.io/s/magical-haze-d71zbj?file=/src/api.ts
