AWS Lambda deployment: Unable to determine region for bucket

Question

I am working on Lambda (NET6) project
When I run the command in Github Actions I receive the error:
`Run dotnet lambda deploy-serverless
Amazon Lambda Tools for .NET Core applications (5.7.0)
Project Home: https://github.com/aws/aws-extensions-for-dotnet-cli, https://github.com/aws/aws-lambda-dotnet
	
Enter CloudFormation Stack Name: (CloudFormation stack name for an AWS Serverless application)
Enter CloudFormation Template: (Path to the CloudFormation template)
Enter S3 Bucket: (S3 bucket to upload the build output)
Warning: Unable to determine region for bucket , assuming bucket is in correct region: BucketName is a required property and must be set before making this call. (Parameter 'GetBucketLocationRequest.BucketName')
Unknown error executing command: Value cannot be null. (Parameter 'path2')
   at System.IO.Path.Combine(String path1, String path2)

`

What should I fix?

Answer

I have added new Policy for my account
{
    "Version": "2012-10-17",
    "Statement": [
        {
            "Sid": "statement1",
            "Effect": "Allow",
            "Action": [
                "s3:CreateBucket",
                "s3:ListAllMyBuckets",
                "s3:GetBucketLocation"
            ],
            "Resource": [
                "arn:aws:s3:::*"
            ]
        }
    ]
}

then run deployment again but the same error occured

Hi, based on https://github.com/aws/aws-lambda-dotnet/issues/262  s3:GetBucketLocation may be missing in the auths that you've currently defined
