TypeError: Cannot read properties of null (reading 'firstChild')

Hi, I am facing this error whenever I hit refresh button in the browser. When I open dashboard screen it works good. I have an app generated with remix, supabase and I removed basic blog_posts and created 1 simple resource

Hi @marcis4977. I'm kapa.ai, your friendly support bot. I will try to answer your question by searching through the knowledge base. :wave: ---------------------- Hmm, I don't know enough to give you a confident answer yet. However, I can suggest some general troubleshooting steps based on the information provided in the extracts. 1. Check your CRUD pages: Ensure that you have correctly implemented the CRUD pages for your resource. These pages should be able to interact with data from the API. You can refer to the documentation (https://refine.dev/docs/packages/documentation/data-providers/supabase) for more details. 2. Check your resource setup: Make sure that you have added your newly created resource to the resources property of the <Refine> component. This activates the connection between CRUD pages and the Supabase API. Here is an example from the documentation (https://refine.dev/docs/packages/documentation/data-providers/supabase/):

<Refine  
  dataProvider={dataProvider(supabaseClient)}  
  resources={[  
    {  
      name: 'yourResourceName',  
      list: "/yourResourceName",  
      create: "/yourResourceName/create",  
      edit: "/yourResourceName/edit/:id",  
    },  
  ]}

<Refine  
  dataProvider={dataProvider(supabaseClient)}  
  resources={[  
    {  
      name: 'yourResourceName',  
      list: "/yourResourceName",  
      create: "/yourResourceName/create",  
      edit: "/yourResourceName/edit/:id",  
    },  
  ]}

3. Check your Supabase setup: Ensure that your supabaseClient is correctly set up with the correct SUPABASE_URL and SUPABASE_KEY. The Refine component's dataProvider, authProvider, and liveProvider objects utilize this supabaseClient to connect to the PostgreSQL server hosted on Supabase. You can refer to this blog post (https://refine.dev/blog/refine-pixels-3) for more details. If the issue persists, it would be helpful to have more specific details about the error you're encountering. ---------------------- Note: you can ask me a follow up question by @ mentioning me again :speech_balloon: ----------------------

Sometimes it works fine, but sometimes it throws this error. @kapa.ai Do you know why?

Let me check the knowledge base for you. One moment! :books: ---------------------- I'm sorry, but without more specific information about the error you're encountering, it's difficult to provide a precise solution. The extracts provided don't contain enough information to diagnose the issue. However, intermittent issues like the one you're experiencing can often be due to network problems, temporary server issues, or race conditions in the code. Here are a few general troubleshooting steps you can take: 1. Check your network connection: Ensure that your internet connection is stable. Network issues can cause intermittent problems when your application tries to communicate with the server. 2. Check the server status: If your application relies on external servers (like a Supabase server), check if there are any known issues or downtime that could be affecting your application. 3. Look for race conditions: In programming, a race condition occurs when the behavior of your software depends on the sequence or timing of uncontrollable events. If your application sometimes works and sometimes doesn't, it could be due to a race condition. For example, you might be trying to use data that hasn't been loaded yet. 4. Check the browser console for errors: If there's an error in your JavaScript code, it might be logged to the browser console. Open the console and refresh the page to see if any errors appear. 5. Debug your code: Use tools like console.log() statements or a JavaScript debugger to step through your code and find out where it's going wrong. If you're still having trouble, please provide more details about the error (such as the exact error message or the part of your code where the error occurs), and I'll do my best to help you solve it. ---------------------- Note: you can ask me a follow up question by @ mentioning me again :speech_balloon: ----------------------
