This error message typically occurs when Ory Oathkeeper cannot find suitable cryptographic keys for the

id_token

mutator. Let's address this issue based on the information provided in the knowledge sources. The

id_token

mutator in Ory Oathkeeper requires a public/private key pair to create a signed JSON Web Token (JWT). To resolve this issue, you need to ensure that you have properly configured and provided the necessary cryptographic keys. Here are the steps to address this: 1. Generate cryptographic keys: Ory Oathkeeper can help you generate the required keys. Use the following command to generate a key for the RS256 algorithm:

docker run oryd/oathkeeper:<version-you-want> credentials generate --alg RS256 > jwks.json

This command will create a JSON Web Key Set (JWKS) file named

jwks.json

[Ory Oathkeeper Documentation](https://www.ory.sh/docs/oathkeeper/configure-deploy#cryptographic-keys). 2. Configure the

id_token

mutator: In your Oathkeeper configuration file (e.g.,

oathkeeper.yml

), ensure that you have properly set up the

id_token

mutator with the correct

jwks_url

. For example:

yaml    mutators:      id_token:        enabled: true        config:          issuer_url: <http://127.0.0.1:4455/>          jwks_url: file:///etc/config/oathkeeper/id_token.jwks.json

Make sure the

jwks_url

points to the location where you've stored the generated

jwks.json

file [Ory Oathkeeper Documentation](https://www.ory.sh/docs/kratos/guides/zero-trust-iap-proxy-identity-access-proxy#id-token-mutator). 3. Verify key accessibility: Ensure that Oathkeeper has read access to the JWKS file. The

jwks_url

can be a local file path or a remote URL. If using a local file, make sure the file permissions allow Oathkeeper to read it. 4. Check key format: The JWKS file should contain the correct key format. The first private key found in the JSON Web Key Set will be used for signing the JWT [Ory Oathkeeper Documentation](https://www.ory.sh/docs/oathkeeper/pipeline/mutator#id_token-configuration). If you've followed these steps and are still encountering issues, you may want to double-check your overall Oathkeeper configuration and ensure that all other required settings are correctly in place. Remember, if you're using asymmetric keys (like RS256), the public key will be available at the

/.well-known/jwks.json

endpoint of your Oathkeeper instance, which can be used by your backend to verify the tokens [Ory Oathkeeper Documentation](https://www.ory.sh/docs/oathkeeper/pipeline/mutator#id_token).

I apologize, but I don't have specific information about using Helm to install Ory Oathkeeper or other Ory products in the provided knowledge sources. The documents don't contain details about Helm installations for Ory services. If you're encountering issues with the

id_token

mutator while using a Helm installation, the general principles I mentioned earlier about configuring the mutator and providing the necessary cryptographic keys still apply. However, the exact steps to implement these in a Helm chart might differ. For the most accurate and up-to-date information on using Helm with Ory products, I recommend checking the official Ory documentation or reaching out to Ory's support channels. They would be able to provide you with specific guidance on Helm installations and configurations.

Sorry @some-animal-25852, I seem to be having a bit of trouble. Don't worry though, I've pinged my support folks and they will try to fix me up! 🧑‍💻 Perhaps try again in 5mins?
