`awssqs` notification service failed due to `InvalidClientTokenId`

[afzal442]

After following the docs along with setting up the aws configuration, awssqs notification svc is not working.
aws sqs test-msg --queue-url https://sqs.eu-north-1.amazonaws.com/5xx16676xxx/test-sqs --message-body '{\"message\": \"hello\"}'
Although I can send msg using the aws CLI, awssqs is showing up operation error on ArgoCD.

{"level":"info","msg":"Sending notification about condition 'on-deployment-ready.[0].9peq5YSISNPOq8LAcQOPwHydZFw' to '{awssqs }' using the configuration in namespace argocd","resource":"myapp-test","time":"2025-06-16T18:56:42Z"}

Plz make sure you have created sqs queue, e.g.
