Bug: Updating configparser_ex to ~> 5.0 creates a version conflict with the ex_aws dependency, which requires ~> 4.0, risking runtime errors during AWS credential parsing.
_{Severity: HIGH}

Suggested Fix

To resolve the version conflict, either update the ex_aws dependency to a version that is compatible with configparser_ex v5.0, or revert the configparser_ex update to a version compatible with ~> 4.0 as required by ex_aws.

Potential issue: The pull request updates `configparser_ex` to version `~> 5.0`, but a
production dependency, `ex_aws` (v2.5.9), requires `~> 4.0`. Because `configparser_ex`
is an optional dependency for `ex_aws`, the build tool might resolve to v5.0. This major
version bump likely introduces breaking API changes. Since the application uses `ex_aws`
at runtime to parse AWS credentials, this version mismatch could cause runtime failures
when `ex_aws` attempts to use the incompatible `configparser_ex` library.
