Extensions being added to imports

[citosid]

I have a few projects that I've been working on and I've been using biome on them since June this year. However, in the past couple of days, it has begin to add .ts to all the local imports.

I cannot find what changed or why it is doing it now. Any clues?

My version is 1.9.4. Here is my config:

{

    { "include": ["**/*.+(controller.ts)"], "linter": { "rules": {} } }
  ]
}

EDIT

This is the problem:

Biome is adding the extension but then my linter (which is also biome) complains. I don't want to configure it to allow for the extensions, since I work with more people and this is not our standard

I think it is coming from useImportExtensions. The rule is enabled because you enabled all rules.

[citosid]

yay! That made it:

  "linter": {
    "enabled": true,
    "rules": {
      "recommended": false,
      "all": true,
      "complexity": {
        "noBannedTypes": "off",
        "noExcessiveCognitiveComplexity": "off",
        "noUselessFragments": "off",
        "useLiteralKeys": "off"
      },
      "correctness": {
      . . .  
      "useImportExtensions": "off",
      . . .
      },
  . . .

I wonder though... why it began failing now?

We promoted 9stabilized) the rule in 1.9.0. You probably used 1.8.0 before upgrading to 1.9.4?
