How to deploy AWS Content Analysis using CloudFormation template?

Hi there,

I tried to install aws-content-analysis a few times but no success. For deployment I sued Cloud Formation template as described here: https://docs.aws.amazon.com/solutions/latest/aws-content-analysis/aws-cloudformation-template.html The user-role that was used in the deployment attempt has administrative permissions. I tried it different regions including us-east-1 and us-west-2.

The error messages are not very descriptive and helpful. Can you assist what could be the possible reasons. Here are the error messages in events tab:

The following resource(s) failed to create: [MieStack]. Embedded stack arn:aws:cloudformation:us-east-1:740403065973:stack/AtifTestStack-MieStack-196PTGLMDBRVL/2ac749b0-802d-11ec-b052-0e6bed256953 was not successfully created: The following resource(s) failed to create: [WorkflowSchedulerLambda]. The following resource(s) failed to create: [WorkflowSchedulerLambda]. Resource handler returned message: "Specified ReservedConcurrentExecutions for function decreases account's UnreservedConcurrentExecution below its minimum value of [50]. (Service: Lambda, Status Code: 400, Request ID: bb972057-2449-411a-b640-c4db2f631f77, Extended Request ID: null)" (RequestToken: 9b8ad42c-bd1e-ca94-557b-b8d9b6cb8d40, HandlerErrorCode: InvalidRequest)

Thanks
