Can't generate TypeScript definitions if message starts with "true"

[j2ghz]

protobuf.js version: 6.11.2

Trying to generate TypeScript definitions for this minimal reproducible example fails:

syntax = "proto3";
message trueWireless {}

Running this succeeds:

node .\node_modules\protobufjs\bin\pbjs -o sample.js -w es6 -t static-module  .\sample.proto

But this fails:

node .\node_modules\protobufjs\bin\pbts -o sample.d.ts .\sample.js
