Worker failing with the error “JavaScript heap memory full.”

Hi, I'm facing a problem with my Cloudflare Worker building process: my NuxtJS build has recently been failing with a “JavaScript heap memory full” error. Everything looks fine at first, but during prerendering, when resvg is supposed to generate the OG images, I get an out-of-memory error:

Sometimes with a big enough project you just have to increase the amount of memory given to Node Take a look at the --max-old-space-size Node option
