How do I suppress warnings when compiling a Business Central Extension - visual-studio-code

Question

I'd like to disable the warning AL1025, because of the nature of the AL compiler, I get a lot of warnings related to my node_modules folder. Apparently, it should be possible to suppress warnings in the app.json like this
"suppressWarnings": ["AL1025"]
But I still get those warnings:
Microsoft (R) AL Compiler version 7.4.7.43721
Copyright (C) Microsoft Corporation. All rights reserved
Compilation started for project 'ABC Sample Ext' containing '11' files at '19:58:7.337'.
/Users/username/Dev/abc-workspace/abc-sample/node_modules/he/LICENSE-MIT.txt(1,1): warning AL1025: The file at location '/Users/username/Dev/abc-workspace/abc-sample/node_modules/he/LICENSE-MIT.txt' does not match any definition.
What am I doing wrong?

You need to define a ruleset that tells the compiler which warnings/errors to ignore.
There are two parts to this:
Define the ruleset
Activate the ruleset
The ruleset is defined in JSON format with a name, description and collection of rules. A rule must have an id, a description and justification.
An example could be:
{
"name": "Custom ruleset",
"description": "Set some rules as hidden",
"rules": [
{
"id": "AL1025",
"action": "Info",
"justification": "Allow non-AL files in workspace"
}
]
}
Then you need to activate the rules you defined. This is done by defining al.ruleSetPath in your settings.json (in the .vscode folder):
{
"al.ruleSetPath": "./custom.ruleset.json"
}
