AWS RDS instance by HTTP Template fails with "[ AWS RDS ] ERROR : 'hmac' undefined."

Attempting to use AWS RDS instance by HTTP Template fails with "[ AWS RDS ] ERROR : 'hmac' undefined." error

I'm running 6.0.12 zabbix server and attempting to collect data from CloudWatch using the "AWS RDS instance by HTTP Template"

https://www.zabbix.com/integrations/aws_rds

The template get AWS RDS instance metrics and uses the script item to make HTTP requests to the CloudWatch AP
I have read the README which seems straight forward.
I have created a user and generated the access-key/secret pair and have updated the following Macros
{$AWS.RDS.INSTANCE.ID}
{$AWS.REGION}
{$AWS.ACCESS.KEY.ID}
{$AWS.SECRET.ACCESS.KEY}
The IAM user policy is defined as the template requires.

The result is no data is collected, and AWS IAM doesn't even report that the user has been used.
The only log that I am seeing is

[ AWS RDS ] ERROR: ReferenceError: identifier 'hmac' undefined

Has anyone else seen success using this template?

Oh I didn't notice. It doesn't look like these templates were introduced until 6.0.13. That's my mistake.

Hello tw-lh

Did you solve the problem by upgrading your zabbix? I'm facing the same problem.
