Cannot find module error after upgrading @swc/core

[sacummings91]

Hello, I recently upgraded @swc/core from 1.3.74 -> 1.3.82. After doing this when I run tests I get Cannot find module '../types/index.js' from '...'. For some reason it is trying to find the file as a .js file instead of a .ts file.

I tested each @swc/core version incrementally and can confirm that it is working up to 1.3.78 but breaks when switching to 1.3.79.

Here are my config files:

.swcrc

{
  "$schema": "https://json.schemastore.org/swcrc",
  "exclude": ["./lib"],
  "jsc": {
    "parser": {
      "syntax": "typescript",
      "tsx": false,
      "decorators": true,
      "dynamicImport": true
    },
    "target": "es2022",
    "paths": {
      "@ternary/api-lib/*": ["./sub-modules/api-lib/src/*"],
      "@ternary/web-ui-lib/*": ["./sub-modules/api-lib/src/ui-lib/*"]
    },
    "baseUrl": "."
  },
  "module": {
    "type": "commonjs"
  }
}

jest.config.js

module.exports = {
  transform: {
    "^.+\\.(t|j)sx?$": "@swc/jest",
  },
  testEnvironment: "node",
  collectCoverage: true,
  moduleNameMapper: {
    "^@ternary/api-lib/(.*)$": "<rootDir>/sub-modules/api-lib/src/$1",
  },
};
