I am running cdk synth in a project with cdk pipelines and it only seems to be synthesising the devops pipeline stack and not the stacks that it deploys. I’m looking in the cdk.out folder. I have been able to deploy and I have on previous occasion seen the other stack files in this folder but something is stopping it from generating them now when I run cdk synth. Their names are printed when I run cdk ls and no errors are returned. If I run cdk synth specific_stack_name it will print to terminal but not produce a file in cdk.out.

My bad: they end up in an assembly folder within cdk.out. I think I saw them in the root before because I had deployed outside of cdk pipelines perhaps.
