[Bug]: AttributeError: 'WebError' object has no attribute '_dispatcher_fiber' #2706
Description
Version
1.49.1
Steps to reproduce
My test-bug.py script:
from playwright.sync_api import sync_playwright
def run(playwright):
browser = playwright.chromium.launch()
context = browser.new_context()
context.on("weberror", lambda error: Exception(f"My page error: {error=}"))
page = context.new_page()
page.set_content("""
<script>var x=null;</script>
<div><button onclick="x.myattr('xxx')">Click me</button></div>
""")
page.get_by_role("button").click()
with sync_playwright() as playwright:
run(playwright)
Expected behavior
The callback:
lambda error: Exception(f"My page error: {error=}")
should be called with the "javascript error from the page"
Actual behavior
The following exception is raised:
