Cloudwatch list-metric-streams CLI call resulting in an InternalFailure

Hello, I'm attempting to list all the metric streams in my account via the list-metric-streams cli call. In every account I have, the call is resulting in "An error occurred (InternalFailure) when calling the ListMetricStreams operation: Unknown".

• The exact call I'm using is "aws cloudwatch list-metric-streams --profile account1 --region us-gov-east-1 ".
• I know that it's not a credentials issue as I can make other calls with the same profile.
• The documentation I've been referencing: https://awscli.amazonaws.com/v2/documentation/api/latest/reference/cloudwatch/list-metric-streams.html
• The errors listed on the page did not give me anymore insight to what the issue is https://docs.aws.amazon.com/AmazonCloudWatch/latest/APIReference/API_ListMetricStreams.html

Any troubleshooting tips? Thanks in advance!
