当在一个群里发送逐条转发超过4张图片时，进程退出

[lincong1987]

以下例子可以重现异常。

Code:

let file = await message.toFileBox().catch (e=>{
    logger.error(e);
    return null;
});

logger.info(`[Get File] [${file.name}] message.toFileBox()`);

let base64 = await file.toBase64().catch ((e)=>{
    logger.info(`[ERROR] [${file.name}] file.toBase64()`);
    logger.error(e);
    return "";
});

if (!fs.existsSync(`${dir_path}${file_path}${file_name}`)) {
    logger.info(`Try Save file to [${dir_path}${file_path}${file_name}]`);
    await file.toFile(`${dir_path}${file_path}${file_name}`,true).catch ((e)=>{
        logger.info(`Save File Fail: ${dir_path}${file_path}${file_name}`);
        logger.error(e);
        file_path="";
    });
    logger.info(`File Saved to ${dir_path}${file_path}${file_name}`);
} else {
    logger.info(`File exist ${dir_path}${file_path}${file_name}`);
}

如果把 await file.toFile 这块代码去除，异常就消失了
