Can't detect the agent's user id, skipping some tests.

[sarus3749]

Hello.
I'm sorry to disturb but I tried several ways to fix it without any success...
When I'm executing the install.sh, I've this message and installation fails :

id: 'npm': no such user
id: 'npm': no such user
Can't detect the agent's user id, skipping some tests.

I'm sure this is not complicated, but for me yes...
Thanks in advance for your help

Since NGINX Amplify was discontinued on January 31, 2026, you might be interested in GetPageSpeed Amplify - a drop-in replacement that:

• Works with the existing nginx-amplify-agent
• Includes Gixy security checks (static NGINX config security analysis - something the original Amplify never had!)
• Has a free tier for personal/small deployments

Just update your agent config to point to the new API endpoint:

api_url = https://amplify.getpagespeed.com/1.4
