with sync_playwright() as pw:
    browser = pw.webkit.launch()
    page = browser.new_page()

    page.context.tracing.start()

    page.context.tracing.stop()

    browser.close()

Describe the bug

When stopping the tracing, playwright throws an error:

Traceback (most recent call last):

This only happens on the new v1.32.0 not on v1.31.1.
