Step function cloud formation issue with Fn::Sub when passing list as second parameter
0
I am trying to create step function using cloud formation. I want to pass the lambda arns as second argument to Fn::Sub function. It works if I pass just one Arn but fails when I pass multiple. (with Fn::Get). I checked the template with Yml validator and did not see any issues.

Fn::Sub takes either a single string as a parameter or a list. When using the list method there should be just two elemenets in the list. The first element is a string (the template) and the second is a map.
From the Fn::Sub documentation
Fn::Sub:
- String
- { Var1Name: Var1Value, Var2Name: Var2Value }
Note: since you are just using Fn::Get attribute to build the substitution value you can just use ${CreateContractFromQuestionnaireFunction.Arn} and use the single string version of Fn::Sub.
E.g. (I've shortened the step function for clarity.
Fn::Sub:|-

I tried referencing them directly using $ and it worked. I get the same error when I remove the second argument completely. I am passing a dummy second argument for now but shouldn't it be optional?

Try:
- { WorkflowStateChangeLambdaArn: {Fn::GetAtt: [ CreateContractFromQuestionnaireFunction, Arn ]}, FailureNotifierLambdaArn: {Fn::GetAtt: [ CreateContractFromQuestionnaireFunction, Arn ]} }Instead of:
- WorkflowStateChangeLambdaArn:
Fn::GetAtt: [ CreateContractFromQuestionnaireFunction, Arn ]
- FailureNotifierLambdaArn:
Fn::GetAtt: [ CreateContractFromQuestionnaireFunction, Arn ]answered Nov 20 '18 at 15:25

Fn::Sub takes either a single string as a parameter or a list. When using the list method there should be just two elemenets in the list. The first element is a string (the template) and the second is a map.
From the Fn::Sub documentation
Fn::Sub:
- String
- { Var1Name: Var1Value, Var2Name: Var2Value }
Note: since you are just using Fn::Get attribute to build the substitution value you can just use ${CreateContractFromQuestionnaireFunction.Arn} and use the single string version of Fn::Sub.
E.g. (I've shortened the step function for clarity.
Fn::Sub:|-
{
"Comment" : "Sample draft process",
"StartAt" : "AdvanceWorkflowToDraftInProgress",
"States" : {
"AdvanceWorkflowToDraftInProgress" : {
"Type" : "Task",
"Resource": "${CreateContractFromQuestionnaireFunction.Arn}",
"InputPath":"$.contractId",
"OutputPath":"$",
"ResultPath":null,
"Next" : "CheckQuestionnaireType",
"Retry" : [

I tried referencing them directly using $ and it worked. I get the same error when I remove the second argument completely. I am passing a dummy second argument for now but shouldn't it be optional?
