Issue in loading image from long long time ago

[stevo-king]

I try to use the api to load an image from long long time ago, but the api cannot load it. I need to scoll on my web whatsapp to trigger the web whatsapp to cache the old image file first, so that I can use the script to load my old image.

May I know if there is any workaround so the whole process can be done on the script?

You can have it automatically open the chat and scroll to the message that contains the image so that it has to load it, you just have to poll it a few times:

            let maxWaitCount = 8;
            let imageWaitInterval = setInterval(function() {
                if (maxWaitCount <= 0) {
                    clearInterval(imageWaitInterval);
                    return;
                }
                maxWaitCount--;
                WAPI.getMessageById(message.quotedMsgObj.id, async (m) => {
                    console.log(m);
                    if (m && m.mediaData.mediaStage === 'RESOLVED') {
                        clearInterval(imageWaitInterval);
                        if (m.mediaData.mediaBlob) {
                            getBase64ImageData(m.mediaData.mediaBlob._blob, (data) => {
                                WAPI.getMessageById(message.id, (m2) => {
                                    m2.quotedMsgObj.body = data;
                                    processMessage(m2);
                                });
                            });
                        }
                        else if (m.type == "sticker") {
                            WAPI.getMessageById(message.id, (m2) => {
                                processMessage(m2);
                            });
                        }
                        else {
                            window.WAPI.downloadFileAndDecrypt({ url: m.clientUrl, type: m.type, mediaKey: m.mediaKey, mimetype: m.mimetype }, (data) => {
                                WAPI.getMessageById(message.id, (m2) => {
                                    m2.quotedMsgObj.body = data.result;
                                    processMessage(m2);
                                });
                            });
                        }
                    }
                    else {
                        let chat = Store.Chat.get(message.chatId);
                        await Store.UiController.openChatBottom(chat);
                        await chat.loadEarlierMsgs();
                        if (m) {
                            Store.UiController.scrollToPtt(m);
                        }
                    }
                });
            }, 3000);

That code has some extra function and I needed a reference to the Ui Controller, you can check out my version of the wapi.js file here:
