I did some googling around for the error message and it looks like you might need to set:
--max-old-space-size to a higher value.

I found these links to be helpful:

Thanks!

Where would you set this up? on every build?

My understanding is that you can set the flag as part of your startCommand on Render.

Example: startCommand: "node --max-old-space-size=102400 ./app.js"

Another option is to set the NODE_OPTIONS env var. Eg:

NODE_OPTIONS="--max-old-space-size=8192"
