Branch: repro/playwright-161-conditions-bug
Folder: repro/

Failing CI (Node 22.15.0): https://github.com/likitakotian/Playwright-Testing/actions/runs/27570859984

Steps:

1. git clone https://github.com/likitakotian/Playwright-Testing.git
2. git checkout repro/playwright-161-conditions-bug
3. cd repro
4. Use Node 22.15.x (required — does NOT reproduce on Node 22.17+)
5. npm ci
6. npx playwright test

Or open the failing GitHub Actions run above.

Expected behavior

Tests load and run.

Actual behavior

Suite fails during module loading:

TypeError: context.conditions?.includes is not a function

Playwright 1.61 sync loader (esmLoaderSync in playwright/lib/common/index.js):

specifier = context.conditions?.includes("import") ? pathToFileURL(resolved).toString() : resolved;

Optional chaining means context.conditions exists but is not an Array.

Node 22.15–22.16 may pass context.conditions as a Set for require()-initiated
resolution in registerHooks: nodejs/node#59003
(fixed in Node 22.17: nodejs/node#59011)

Related: #41121 / #41138 (same line, Windows file:// case).

Suggested fix:
const isImport = context.conditions?.has?.('import') ?? context.conditions?.includes?.('import');
