Error with pixelmatch ES import into an ES Playwright test

[manudas]

Hi there

I am trying to use Pixelmatch 6.0 (ES module pixelmatch) on a TS project

It shouldn't be a problem, however, when importing it in a Playwright test, I get this problem in the beginning of the test file (not even in the import statement):

Error: require() of ES Module C:\Sources\RTCP.DepTMS\WebClient\PlanReview\BlueEthos.Web.UI\node_modules\pixelmatch\index.js from C:\Sources\RTCP.DepTMS\WebClient\PlanReview\BlueEthos.Web.UI\playwright\tests\integration\plan-review.spec.ts not supported. Instead change the require of index.js in C:\Sources\RTCP.DepTMS\WebClient\PlanReview\BlueEthos.Web.UI\playwright\tests\integration\plan-review.spec.ts to a dynamic import() which is available in all CommonJS modules.playwright

Following the advice to use a dynamic import it works, but I don't understand why, as this is not a CommonJS module.

I've removed the @types/pixelmatch module as it was for a previous CommonJS version, but no luck.

What could be happening? this is a non sense.

Let me know if I can do some checks to find out what the problem is.
Thanks
