Frequently Getting this error while trying to build ASEA

[Shashkan]

Error log:
ASEA-InitialSetup | 4:51:50 PM | CREATE_FAILED | AWS::IAM::Role | Pipeline/Role (PipelineRoleD68726F7) Invalid principal in policy: "AWS":"arn:aws:iam::ID:role/ASEA-L-SFN-MasterRole-F5D3DE56" (Service: AmazonIdentityManagement; Status Code: 400; Error Code: MalformedPolicyDocument; Request ID: 576818a9-0a20-4e2c-a179-30cc48e71978; Proxy: null)

I swapped the actual id..

Not able to understand this error and role: ASEA-L-SFN-MasterRole-F5D3DE56.

Followed all the ASEA implementation steps and made changes to my config.json.
I am using Github json tempalate to trigger my cloud formation stack.

I checked my policy too in KMS, its:
{
"Sid": "Enable IAM User Permissions",
"Effect": "Allow",
"Principal": {
"AWS": "arn:aws:iam::Id:root"
},
"Action": "kms:",
"Resource": ""
},

Please any help would be appreciated.
