Node.js --cpu-prof flag: Failed to convert CPU profile message to V8 string

Question

I'm using the --cpu-prof flag to generate a cpuprofile of my Node.js 18.16.0 application. When I try to initiate the creation of the cpuprofile, I get this error: Failed to convert CPU profile message to V8 string.

I'm hosting my app in a Docker container within Azure App Service. This error hasn't appeared anywhere else on the Internet - What does it mean, and how can I resolve it?

Dockerfile:

FROM node:18-alpine AS builder
WORKDIR /build

COPY . .

RUN npm ci

RUN npm run compile

CMD ["npm", "start"]
