[Extension/Formatting] FATAL ERROR: Reached heap limit Allocation failed - JavaScript heap out of memory

[ellaroosmarijn]

Bug description

Hello, I have a stock installation of prisma@5.18.0 and an extension of the same version. My prisma schema file is in the usual place (prisma/schema.prisma). My VSCode settings are as recommended in this document.

When I attempt to format my schema.prisma file VSCode loads for around 30 seconds and the following is dumped to the VSCode output:

Finally, the document is not formatted.

How to reproduce

Not sure it's just happening... 😬 I've tried install and uninstalling VSCode and the extension several times, and have upgraded the prisma npm packages.

Expected behavior

It formats the document.
