Deploy issue - CALL_AND_RETRY_LAST allocation failed javascript heap out of memory

I have my project (https://tyton.io) set up in a CI pipeline on GitLab. It’s been running fine for months. Today I updated the project to meteor 1.6.0.1 and although the test job passed the deploy script is failing. Here’s a screenshot of the output

Seems to be failing with “CALL_AND_RETRY_LAST allocation failed javascript heap out of memory”.

Any ideas how to troubleshoot/resolve this?

Do you update your node version ?
