I found a similar unsolved discussion titled Help Problem starting the project which might be related to the issue you're experiencing ^[1].

Regarding the error message you're encountering, the TypeError: Promise.withResolvers is not a function suggests that there might be an issue with the usage of Promise.withResolvers in the code. This function might not be available or correctly imported in your environment.

To troubleshoot this issue, consider the following steps:

1. Check for Updates: Ensure that all dependencies are up-to-date. There might be a missing or outdated package that provides the Promise.withResolvers function.

2. Review Code: Look into the specific files mentioned in the error log (19063.js, 25039.js, 50007.js, and page.js) to identify where Promise.withResolvers is being used. Verify if it's correctly implemented or if an alternative approach is needed.

3. Environment Configuration: Double-check your Docker setup and environment variables to ensure everything is configured correctly. Misconfigurations can sometimes lead to unexpected errors.

4. Consult Documentation: If Promise.withResolvers is a custom utility function, refer to the project's documentation or codebase to understand its intended use and implementation.

If these steps do not resolve the issue, further investigation into the specific implementation of Promise.withResolvers in your codebase might be necessary.

Just to clarify, I didn't make any changes to the .env file (for example, APP_WEB_URL remained the same as before). I only added some new variables. Everything was working fine prior to this, but after upgrading to the main version yesterday, the webapp started acting abnormally.

I tried using chat and workflow, tested multiple Dify projects, and even attempted updating the webapp's URL, but none of these efforts worked.

@XiaoLey It seems that the react-pdf-highlighter component references pdfjs, and this component is not compatible with Node 20. You might consider using Node 22 to rebuild the image or downgrading the component.

澄清一下，我没有对文件进行任何更改（例如，与以前相同）。我只添加了一些新变量。在此之前一切正常，但是昨天升级到主版本后，网络应用程序开始运行异常。.env``APP_WEB_URL

我尝试使用聊天和工作流程，测试了多个 Dify 项目，甚至尝试更新 Web 应用程序的 URL，但这些努力都没有奏效。

Also experiencing this issue, WebApp is not working

@fsea just upgrade node version to 22
