The thirty-two library is deprecated, uses the deprecated new Buffer(...) constructor in several places.
This usage is deprecated and should be replaced with Buffer.from(...) for safety and compatibility with modern Node.js versions.

/node_modules/.pnpm/@[email protected]/node_modules/thirty-two/lib/thirty-two/thirty-two.js

To safely replace the deprecated new Buffer(...) usage, use Buffer.from(...) instead.
How to update:
Replace new Buffer(plain) with Buffer.from(plain)
Replace new Buffer(quintetCount(plain) * 8) with Buffer.alloc(quintetCount(plain) * 8)
Replace new Buffer(encoded) with Buffer.from(encoded)
Replace new Buffer(Math.ceil(encoded.length * 5 / 8)) with Buffer.alloc(Math.ceil(encoded. Length * 5 / 8))
