Cache does not work within parent#child pipeline

Describe your question in as much detail as possible:
My cache does not work properly - it does not save some folders and do not use SHA as key

• What are you seeing, and how does that differ from what you expect to see?
  I have inside child pipeline install_dependencies job which should create cache of 2 folders (node_modules and .yarn) based on yarn.lock content.
  This job should run only when yarn.lock is changed.
  All underline test/build jobs just use cache as is.

Now

• I do not see any hash in cache file name
• .yarn folder is missing in later jobs

• Consider including screenshots, error messages, and/or other helpful visuals
