DataZone Cloudformation Stack

Question

Hi, I'm trying to create a DataZone Setup through Cloudformation templates. I've cretaed the DataZone domain, project and Envrionment Blueprint Configuration, however, when trying to proceed with Environment profile, I get this error:

"Properties validation failed for resource AdviceClientEnvironmentProfile with message: #/ProjectIdentifier: failed validation constraint for keyword [pattern] #/EnvironmentBlueprintIdentifier: failed validation constraint for keyword [pattern]"

This is how I'm trying to define my resource:

AdviceClientEnvironmentProfile:
    DependsOn: AdviceClientBlueprintConfig
    Type: AWS::DataZone::EnvironmentProfile
    Properties:
      AwsAccountId: !Ref AWS::AccountId
      AwsAccountRegion: us-east-1
      DomainIdentifier: !Ref AdviceDomain
      EnvironmentBlueprintIdentifier: !Ref AdviceClientBlueprintConfig
      Name: advice_environmentprofile
      ProjectIdentifier: !Ref AdviceClientProject

Kindly suggest where the template is going wrong.

Thanks,
Diksha

Hi,

As per documentation, `EnvironmentBlueprintIdentifier` must match a given pattern that you `!Ref AdviceClientBlueprintConfig` doesn't probably follow. Hence the error message that you get.

See https://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/aws-resource-datazone-environmentprofile.html#cfn-datazone-environmentprofile-environmentblueprintidentifier

```
EnvironmentBlueprintIdentifier
The identifier of a blueprint with which an environment profile is created.
Required: Yes
Type: String
Pattern: ^[a-zA-Z0-9_-]{1,36}$
```
Investigating a bit further, you cannot use `!Ref AdviceClientBlueprintConfig` as EnvironmentBlueprintIdentifier because based on docs of `AWS::DataZone::EnvironmentBlueprintConfiguration`, !Ref functions returns `DomainId|BlueprintConfigurationId` with a pipe character (i.e. | ) in the middle. This char is not allowed by the pattern above.

See https://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/aws-resource-datazone-environmentblueprintconfiguration.html#aws-resource-datazone-environmentblueprintconfiguration-return-values

So, adapt `!Ref AdviceClientBlueprintConfig` (=parse it to remove |) to match this pattern or use another identifier and your issue will be solved.

Best,

Didier
