Brief summary

k6-browser is throwing various non-repeating errors using the non-experimental k6/browser usually seen within calls to page.evaluate

k6 version

0.55.0

OS

macOS 15.1.1

Docker version and image (if applicable)

docker.desktop 4.35.1 (173168)

Steps to reproduce the problem

Here is an excerpt of our sendSocketChatMsg function that works as expected with the k6/experimental/browser but inevitably panics in different ways within the evaluated callback when using the stable k6/browser. I will post some of the panics I am seeing in the Actual Behavior section

export const generateUUID = () => {
    // UUIDv4 pattern: xxxxxxxx-xxxx-4xxx-yxxx-xxxxxxxxxxxx
    return "xxxxxxxx-xxxx-4xxx-yxxx-xxxxxxxxxxxx".replace(/[xy]/g, function (c) {
        const r = (Math.random() * 16) | 0,
            v = c == "x" ? r : (r & 0x3) | 0x8;
        return v.toString(16);
    });
};

const isSpecialChatDestination = (msgTo: string) => {
    return Object.values(DISPLAY_NAMES).includes(msgTo as DISPLAY_NAMES);
};

export const sendSocketChatMsg = async (page: Page, robotName: string, msg?: string, msgTo?: string) => {
    try {
        const id = generateUUID();
        let specialDestination;
        if (!msgTo) {
            // eslint-disable-next-line no-param-reassign
            msgTo = DISPLAY_NAMES.ROOM as string;
            specialDestination = true;
        } else if (msgTo === "Staff") {
            // eslint-disable-next-line no-param-reassign
            msgTo = DISPLAY_NAMES.STAFF_IN_ROOM as string;
            specialDestination = true;
        } else if (msgTo === "Room") {
            // eslint-disable-next-line no-param-reassign
            msgTo = DISPLAY_NAMES.ROOM as string;
            specialDestination = true;
        } else {
            // check for special destination:
            specialDestination = isSpecialChatDestination(msgTo);
        }
        console.log(`${new Date().toISOString()} ${robotName} %%%% call page.evaluate for chat`, {
            robotName,
            msg,
            msgTo,
            id,
            specialDestination,
        });
        await page.evaluate(
            (data) => {
                let userName: string;
                try {
                    const studentSocketConnectionInstance = window.globalSocketConnection.getInstance();
                    if (!studentSocketConnectionInstance) {
                        return { rc: -1, err: "No socket found" };
                    }
                    const studentState = window.globalStudentState;
                    let name;
                    if (data.specialDestination) {
                        // room, staff etc, no lookup needed
                        userName = data.msgTo;
                        name = data.msgTo;
                    } else {
                        const targetUser = studentState.participants.find((x: any) => x.name.startsWith(data.msgTo));
                        userName = targetUser?.userName;
                        name = targetUser?.name;
                    }
                    const message =
                        data.msg && userName
                            ? data.msg
                            : !userName
                              ? `FAILED TO FIND RECIPIENT: ${data.msgTo} for msg (${data.msg})`
                              : "No message text found";
                    studentSocketConnectionInstance
                        .sendChatMessage({

                            shouldNotify: false,
                        })
                        .then((res: any) => console.log("Send Chat res:", res))
                        .catch((err: Error) =>
                            console.log(

                        .finally(() => null);
                    console.log(data.robotName, "CHAT from socket done");
                    return 0;
                } catch (err) {
                    console.log("ERROR: robot chat msg send", data, err);
                    return { rc: -1, err };
                }
            },
            { robotName, msg, msgTo, id, specialDestination },
        );
        console.log(`${new Date().toISOString()} ${robotName} %%%% call page.evaluate for chat: DONE`);
        return 0;
    } catch (err) {
        console.error(
            `${new Date().toISOString()} ${robotName} ERROR sendSocketChatMsg`,
            err,
            (err as Error).toString(),
            { msg, msgTo },
        );
        return { rc: -1, err };
    }
};

Expected behaviour

This works as expected with the old k6/experimental/browser the call to studentSocketConnectionInstance.sendChatMessage is successful.

Hi @adamgrant-engageli,

Any chance you could send us a full test script that exhibits this issue when working with k6/browser vs k6/experimental/browser? I can't see anything obvious that could cause any issues or replicate the issue with the excerpt you have given us. Also, what version of k6 are you running?

k6 version 0.55.0
I will try to get permission to share the test library sources.
