Report #62375

[bug\_fix] AWS SDK throws InvalidIdentityToken: No OpenIDConnect provider found in your account for https://oidc.eks.region.amazonaws.com/id/XXX

Create the OIDC Identity Provider in AWS IAM using the EKS cluster's OIDC issuer URL \(found in the EKS console or via 'aws eks describe-cluster'\) and the required thumbprint \(typically the root CA thumbprint for the certificate, or use 'eksctl utils associate-iam-oidc-provider'\). This allows STS to validate the JWT identity token issued by EKS to the pod.

Journey Context:
Developer sets up IRSA \(IAM Roles for Service Accounts\) for an EKS pod. They annotate the service account with the IAM role ARN and configure the pod. When the application starts, it receives the AWS\_WEB\_IDENTITY\_TOKEN\_FILE env var and attempts to call STS AssumeRoleWithWebIdentity. It fails with InvalidIdentityToken. Developer checks the IAM role's trust policy, ensuring it trusts the service account ARN. Policy looks correct. They examine the JWT token in the pod, it looks valid with 'iss': 'https://oidc.eks.us-west-2.amazonaws.com/id/ABCDEF'. They check IAM Console > Identity Providers and realize the list is empty. The OIDC provider for the EKS cluster was never created. They run 'eksctl utils associate-iam-oidc-provider --cluster my-cluster --approve' which creates the OIDC IdP in IAM with the correct URL and thumbprint. The pod restarts and STS successfully validates the token against the now-existing IdP, allowing the AssumeRole to succeed.
