HitomiError [REQEUST_REJECTED]: Request to 'https://ltn.hitomi.la/gg.js' was rejected about node-hitomi

Okay, I made a handler for the promise and will keep investigating what made the request go wrong.
I published new release, please check the package's new version.

[H2Owater425]

Since the request problem wasn't solved, I guess it's fine to keep this issue open.
Just let me investigate this problem's cause.

[H2Owater425]

Hmm... I couldn't find any problems with tests on various node versions.
Have you checked your internet connection? (Or perhaps Hitomi's server could have gone down while you writing that code)

[dnm13]

which function made a request for https://ltn.hitomi.la/gg.js ?
I'd like to try something with try-catch, can you tell me which one?

[H2Owater425]

Since the data of that page is related to generating the image url, synchronize method of ImageUrlResolver instance makes a request.
Additionally, I want you to check if you can access that page manually with your browser or something.
Sorry that I couldn't be of any help, I hope you find out the problem.

[dnm13]

.catch didnt work. The error bleeds to the process.

const getImageUrl = async function getImageUrl(image: hitomiType.Image, extension: "avif" | "webp", options: { isThumbnail?: boolean | undefined; isSmall?: boolean | undefined; }) {
    if (!IUR) {
        const hitomi: typeof hitomiType = require("node-hitomi").default;
        IUR = new hitomi.ImageUrlResolver();
        await IUR.synchronize().catch((err: Error) => {
            console.log("Error catch from synchronize");
            console.log(err.message);

        }); // first synchronize
    }
    return await IUR.getImageUrl(image, extension, options);
}

// ...

CPM.registerJob("hitomi:startup", () => {
    setInterval(() => {
        if (IUR) IUR.synchronize().catch(
            (err: Error) => {
                console.log("Error catch from synchronize");
                console.log(err.message);
            });
    }, SynchronizeInterval);
});

console:

To be clear, I'm able to access hitomi.la without any problem, and my app was able to fetch some image before the error was thrown.

I was also able to access https://ltn.hitomi.la/gg.js on my browser.

I'll try with try-catch statement for now, hopefully the error doesn't bleed to the process.

[dnm13]

Nope, try-catch didn't work either

const getImageUrl = async function getImageUrl(image: hitomiType.Image, extension: "avif" | "webp", options: { isThumbnail?: boolean | undefined; isSmall?: boolean | undefined; }) {
    if (!IUR) {
        const hitomi: typeof hitomiType = require("node-hitomi").default;
        IUR = new hitomi.ImageUrlResolver();
        try {
            await IUR.synchronize().catch((err: Error) => {
                console.log("Error catch from synchronize");
                console.log(err.message);

            }); // first synchronize
        }
        catch (err) {
            console.log("Error catch from try-catch synchronize");
            console.log(err.message);
        }
    }
    return await IUR.getImageUrl(image, extension, options);
}

CPM.registerJob("hitomi:startup", () => {
    setInterval(() => {
        if (IUR) {
            try {
                IUR.synchronize().catch(
                    (err: Error) => {
                        console.log("Error catch from synchronize");
                        console.log(err.message);
                    });
            }
            catch (err) {
                console.log("Error catch from try-catch synchronize");
                console.log(err.message);
            }
        }
    }, SynchronizeInterval);
});

Same error, not going to post it again here to avoid spamming

[dnm13]

I believe the most important thing to fix here is the fact that the error can't be catch on both .catch and try-catch statement.
Because it somehow immediately broke my loop (the code was run in for loop, but the .synchronize() was in interval of every 10 minutes)

[dnm13]

I suggest to add .catch() here:

Code:

IUR.synchronize().catch(err => { console.log("Catched an error from synchronize: ", err); return Promise.reject(err) });

Console:

Catched an error from synchronize:  HitomiError [REQEUST_REJECTED]: Request to 'https://ltn.hitomi.la/gg.js' was rejected

Retrying...

Notice that after the error was catched, the loop continues and it retries the operation.
Although idk why the error was logged twice, but hey it works and doesn't breaks the loop.

Edit: nvm, the error was logged twice because the root caller was also logging the error on Promise reject.

[dnm13]

Okay, the error now can be catched
Should I leave this issue open? because although the error can be catched now, it doesn't actually solve the main problem
