Exception schema with key or id "C:\Users\ybagriy\sources\scripts\Clients\Client.yaml" already exists is thrown by ajv. I'm not familiar with it enough to understand why it's happening only on windows.

So far this exception occurs only with this validation rule, any other seems to be passing fine on our project repo.

[slavikbez]

On Windows it won't throw if I comment this line. Will investigate deeper.

[tatomyr]

For some reason Ajv visits Clients\Client.yaml twice on Win. It happens when validating the /clients path. The data we provide for validation is identical for both Win & Mac. The bundles are equal too.

@tatomyr any news on this one?

[tatomyr]

@jeremyfiel unfortunately I cannot share any ETAs on this at the moment.

[laellyo]

Hello,
I have the same issue on Windows.
Any idea at least of a workaround? (Except disabling the rule 🙃)

[tatomyr]

Hi @laellyo,
Maybe ignoring these exact errors could help in your case? Please see the docs: https://redocly.com/docs/cli/commands/lint/#generate-ignore-file
This won't help with validating the content of a ref though.

[morozovcookie]

Hello, everyone! Are you sure that this is only on windows? I run redocly in docker with image redocly/cli:v1.0.0-beta.123 and I just got the same error.

@tatomyr @lornajane any update on this one? It's still occurring for all examples with shared schemas. I'm on win 10.
