Aws cdk pipeline stacks keep creating buckets on every deploy

Question

Is there a way to restrict this? I'm not talking about artifact buckets, but everytime I do cdk deploy for my pipeline stack it's creating a bucket. Is there a way to limit this to a single bucket or something, does anyone know what's causing this?

My cdk stack has a codepipeline stack it creates, and every time there's a change released on the pipeline it will create another bucket, and it creates a lot of clutter very quickly. Is there any way to limit it to a single bucket? cdk stack code: https://pastebin.com/XgcLNxsL
