Running into this error when installing packages with

yarn

:

ERROR: error graphql@16.2.0: The engine "node" is incompatible with this module. Expected version "^12.22.0 || ^14.16.0 || >=16.0.0". Got "14.15.4"

Is it possible to specify the node version for a build?

You can pin the node version by adding a buildspec. Here's an example https://seed.run/blog/node-v14-support.html

That works perfectly. Thanks Frank! 👍
