I'm spending two days because of this trouble.

I have Cloud Build setting already but am trying to insert test process into Cloud build on GCP.

so, here's what I've added,

- name: gcr.io/cloud-builders/yarn
  args: ['install']
- name: gcr.io/cloud-builders/yarn
  args: ['test:unit']

but I got an error error @grpc/grpc-js@0.6.9: The engine “node” is incompatible with this module. Expected version “8.13.0 || >=10.10.0”. error Found incompatible module

I don't seriously know why it happened. Do I have to install node at the previous step? Or just sync the node engine version? If yes, how do I set node engine version?

I've already done --ignore-engines at install but even the error is occurred when testing...

What points am I missing? and how can I figure it out?
