Firebase CLI Emulator Startup Issue

Environment Information

  • Firebase Tools Version: 13.29.0
  • NodeJS: 20.11.1
  • Platform: macOS
  • Project: codelab-dataconnect-web

Issue Description

The Firebase emulator fails to start with a runtime error when attempting to initialize the Data Connect emulator's PostgreSQL database.

Steps to Reproduce

  1. Clone the repository: 
    git clone https://github.com/firebaseextended/codelab-dataconnect-web
  2. Navigate to the app directory and install dependencies: 
    cd app
npm i
  3. Start the Firebase emulators: 
    firebase emulators:start

Expected Behavior

  • Firebase emulators should start successfully
  • Data Connect emulator should initialize properly with PostgreSQL database

Actual Behavior

The emulator fails to start with the following error:

RuntimeError: unreachable
    at wasm://wasm/0222924a:wasm-function[5692]:0x42e8d4
    at wasm://wasm/0222924a:wasm-function[5668]:0x429e8f
    at wasm://wasm/0222924a:wasm-function[2877]:0x25097d
    at Module._pg_initdb (/usr/local/lib/node_modules/firebase-tools/node_modules/@electric-sql/pglite/dist/index.cjs:12:118235)

Additional Notes

  • Multiple emulator instances warning was observed
  • The issue appears to be specific to the Data Connect emulator's PostgreSQL initialization
  • Full logs from running command with --debug flag:
