How to deploy 20 lambdas into multiple environments like Test, Staging and Production

In our architecture, we have to deploy 20 lambdas, each lambda is deployed through a separate template which is in root folder of the code and we have three different environments like Test, Staging and Production. When i tried to deploy lambda1 in 3 environments, it is working fine, but when i try to deploy lambda2 into 3 environments, getting error like environment defined multiple times. Please find the sample code and error attached here. Any help for this solution is highly appreciated. Thanks in advance.

pipelines:
  default:
        - step:
            name:  lambda1 deployement
            deployment: Test

              - node

If I do so the error is like, defined test or staging or production in multiple times. How can i deploy 20 lambdas whenever there is a change in the corresponding code. Please suggest. Thank you
