JavaScript heap out of memory error on Raspberry Pi 3B+

[mezakos]

I'm trying to run dashy on a Raspberry Pi 3B+ with docker. I'm using the lissy93/dashy:arm32v7 image. The container is not able to start up because during the yarn build process I get the following error:

FATAL ERROR: Ineffective mark-compacts near heap limit Allocation failed - JavaScript heap out of memory
