How to properly click "Save" button in a Doctype form using Playwright?

I’m doing a test case using Playwright, but after filling up the form fields for some reason, it won’t let me click the “Save” button
I tried:

        await page.locator('btn-primary').click();
        await page.locator('button[data-label="Save"]').click();
        await page.click('button[data-label="Save"]');

But it won’t work in playwright please help if anyone knows? Thanks in advance.
