This pull request fixes a bug in the process of composing executions' arn when
grantRead()
andgrantExecution()
methods are called on aIStateMachine
construct.This bug assigned a wrong arn to resources referenced in the IAM policy when the
IStateMachine
was imported from a different account or region than the current stack.The private
executionArn()
method now uses all arn components of theIStateMachine
to build the arn string, rather than leavingaccount
andregion
components to the default values.Fixes #17982
