Error: net::ERR_ACCESS_DENIED on /@mermaid-js/mermaid-cli/dist/index.html

[qzhuyan]

Describe the bug just run simple example code give me error as following:

Error: net::ERR_ACCESS_DENIED at file:///home/ubuntu/.asdf/installs/nodejs/21.6.0/lib/node_modules/@mermaid-js/mermaid-cli/dist/index.html

but the file has the right permissions (cat file also works), suspect the error code is miss translated.

ls -alt /home/ubuntu/.asdf/installs/nodejs/21.6.0/lib/node_modules/@mermaid-js/mermaid-cli/dist/index.html

To Reproduce

Steps to reproduce the behavior:

@jmruiza, it seems like your issue is unrelated.

Can you access https://registry.npmjs.org/@mermaid-js%2fmermaid-cli in your browser?

It seems like you might have internet connectivity issues with npm. It might be worth looking at https://github.com/npm/npm/issues/17064 or https://stackoverflow.com/q/28722515 for tips on how to fix it.

Is there any update on how to fix this error? I've spent a few hours following links and trying to figure out what's causing this, without any luck. System is a fresh Ubuntu 24.04.

I don't get any errors installing with "npm install -g @mermaid-js/mermaid-cli". When I try to run a simple conversion, as shown in the top post of this thread, I get the net::ERR_ACCESS_DENIED error.

I've done the following:

• disabled ipv6 on the system
• verified there is no proxy configured (npm config delete proxy, npm config delete http-proxy, npm config delete https-proxy)
• verified the system has no problems accessing https://registry.npmjs.org/@mermaid-js%2fmermaid-cli (using curl and output to file)
• updated the node version to v22.5.1
• Checked permissions on the files in ~/.nvm/versions/node/v22.5.1/node_modules

I'm running out of ideas and things to try. This seems way harder to get running than it should be. The specific error I get is:

I found the root cause and fix.

I get kernel print out from dmesg

...  apparmor="DENIED" operation="open" profile="snap.chromium.chromium" ...

So it is the apparmor manages the permissions.

After I append a rule to allow access @{HOME}/.asdf/installs/nodejs/ in the file /var/lib/snapd/apparmor/profiles/snap.chromium.chromium

like

# Layout path: /usr/share/xml/iso-codes
"/usr/share/xml/iso-codes{,/**}" mrwklix,
owner @{HOME}/.asdf/installs/nodejs/** r,
}

then reload it with command

sudo apparmor_parser -r /var/lib/snapd/apparmor/profiles/snap.chromium.chromium

then it works

cat << EOF  | mmdc --input -
    graph TD
    A[Client] --> B[Load Balancer]
EOF
