Thanks for your reply, @nandorsoma. In our case, it's a bit complicated, we use NiFi in AWS EKS. Due to permissions issues, the ops will provide me with a service account that has the IAM role authenticated by OIDC, this service account will add an ENV: `AWS_WEB_IDENTITY_TOKEN_FILE : /var/run/secrets/eks.amazonaws.com/serviceaccount/token` to the Pod. In the NiFi, I use the `AWSCredentialsProviderControllerService` processor and by setting `Use Default Credentials` to `true`, then I can read the temporary permissions provided by the STS to access AWS related services. Without this environment variable, the `AWSCredentialsProviderControllerService` will report an error: ``` 2023-03-14 15:56:44,700 DEBUG [Timer-Driven Process Thread-2] c.a.auth. AWSCredentialsProviderChain Unable to load credentials from WebIdentityTokenCredentialsProvider: To use assume role profiles the aws-java-sdk- sts module must be on the class path. ``` I think the key is the AWS_WEB_IDENTITY_TOKEN_FILE environment variable, which the AWS client will use to get the information it needs.
