Report #9636

[bug\_fix] WebIdentityErr: failed to retrieve credentials caused by: InvalidIdentityToken: No OpenIDConnect provider found in your account for https://oidc.eks.region.amazonaws.com/id/EXAMPLED539D4633E53DE1B716D3041E

Create an IAM OpenID Connect \(OIDC\) Identity Provider in the AWS account with the URL matching the EKS cluster's OIDC issuer URL \(found in the EKS console\), and set the audience to \`sts.amazonaws.com\`. Root cause: When using IAM Roles for Service Accounts \(IRSA\), the Kubernetes service account token is a JWT signed by the EKS cluster's OIDC issuer. AWS IAM needs a trust relationship with that OIDC provider to validate the JWT signature and issue temporary STS credentials; without the IdP, the STS AssumeRoleWithWebIdentity call fails.

Journey Context:
Developer configures a pod with a service account annotated with \`eks.amazonaws.com/role-arn: arn:aws:iam::123:role/my-role\`. The pod starts but the application gets credentials error. Developer checks pod logs: 'InvalidIdentityToken: No OpenIDConnect provider found'. They check the IAM role's trust policy - it references the correct OIDC URL and service account. They realize the OIDC provider itself is missing from the account. They go to IAM > Identity Providers > Add Provider. They enter the URL from the EKS cluster overview \(oidc.eks.region.amazonaws.com/id/XXXX\). They use audience 'sts.amazonaws.com'. They create the provider. The pod \(after restart\) now successfully assumes the IAM role via the projected service account token.
