Pega to S3 connection failing
While connecting to s3 from pega dev studio via repository rule we are seeing below issue
The specified folder exists, but you have Insufficient permissions to read from it.
While connecting for server we are able to connect.

This error usually happens because the AWS IAM role or user that Pega is using does not have the right permissions on the S3 bucket or folder. Even though the bucket exists, Pega needs both s3:ListBucket and s3:GetObject permissions on that path. Check the repository rule configuration in Pega Dev Studio and confirm that the access key/secret key or IAM role mapped to it has a proper bucket policy attached. If you are using a specific folder inside the bucket, ensure the policy explicitly allows access to that folder path. Also, make sure the bucket region in Pega matches the actual S3 bucket region. Since server-side connection works, this points to Pega’s configured credentials lacking folder-level read access. Fixing the IAM policy or updating the repository rule with correct credentials should resolve it.
