Bug Description
A TypeError occurs in get_open_tabs_info function when constructing the server URL. The error message states: can only concatenate str (not "int") to str, which happens when trying to concatenate the integer port number directly with strings.

Location
File: desktop_env/evaluators/getters/chrome.py, line ~531

Current Code

requests.post("http://" + host + ":" + server_port + "/setup" + "/launch", headers=headers, data=payload)

Proposed Fix
Convert the port number to string or use f-string:

requests.post(f"http://{host}:{server_port}/setup/launch", headers=headers, data=payload)

Additional Notes

• This issue occurs because server_port is an integer while string concatenation requires all operands to be strings
• The fix ensures proper type handling when constructing the URL string
• Using f-strings also makes the code more readable and less prone to such concatenation errors
