Pipeline not triggering per branch

Question

I have added branch specific steps to build the image for nodejs application, here is the pipeline

options:
 docker: true

pipelines:
 branches:
   dev:
     - step:
       name: Build Prod Image
       image: node:9.50
       services:
         - docker
       script:
         - npm install
         - npm run buildtest

"dev" branch is available, if I add "default" block that is getting executed for master branch commit. Please let me know if this pipeline is wrong or any hint what might be going wrong

I don't know if it is how you copied/pasted the yml file here, but the above is still an invalid format.

I have verified from the same validator still not working, here is the updated one

Looks like you have an indentation error in your yml file after the `- step` block, you need to put child blocks with more white-space for them to get correctly recognized.

Please use online validator when you are not sure.
