Web Search Functionality Not Working Due to Playwright Error on Azure web app

[pronitagrawalvera]

The web search functionality in Chat UI is failing due to a missing Playwright browser executable. The error log indicates that Playwright is unable to find the required Chromium headless shell.

I tried running npx playwright install but still it is not wokring

Can I ask how you're deploying the app? With docker or directly from source?

Hi @nsarrazin ,

From the docker file, Sharing my Docker file details

# Use Node.js version 20 as the base image
FROM node:20 as base-node-image

# Update the package list, install necessary packages, and clean up
RUN apt-get update && \
    apt-get install -y --no-install-recommends vim gnupg curl openssh-server links lsof && \
    rm -rf /var/lib/apt/lists/*

# Set up SSH
RUN echo "root:Docker!" | chpasswd && \
    mkdir /var/run/sshd

# Set the working directory
WORKDIR /home/site/wwwroot

# Copy package.json and package-lock.json
COPY package.json ./
#COPY package-lock.json ./

# Install dependencies
RUN npm install

# Clean npm cache
#RUN npm cache clean --force

# Install dotenv-cli globally


# Copy the rest of the application
COPY . .

# Uncomment if you have a build step
# RUN npm run build

# Make the entrypoint script executable
RUN chmod +x /home/site/wwwroot/entrypoint.sh

# Expose application port
EXPOSE 3000 22 5173

Any reason not to use the official docker images we provide? This should work since that's the one we use for HuggingChat.

Okay @nsarrazin I will try this and get back to you.
