Hi @Bernd Bammer. I'm, your friendly support bot. I will try to answer your question by searching through the knowledge base. :wave: ---------------------- I'm sorry to hear that you're experiencing issues with the tutorial. Based on the knowledge sources provided, there are a few reported issues with the tutorials on the refine documentation. For example, there's an open issue on GitHub about a broken tutorial on the UI libraries section (source ( However, the specific error you're encountering ("Invalid left-hand side in assignment") isn't directly mentioned in the provided sources. This error typically occurs in JavaScript when you try to assign a value to something that isn't a valid variable, such as a number or a function call. Without more specific information about the code causing this error, it's hard to provide a definitive solution. I would recommend checking your code for any such invalid assignments. If you're still having trouble, you might find it helpful to raise an issue on the refine GitHub repository ( The maintainers and community are usually quite responsive and may be able to help you resolve the issue. ---------------------- Note: you can ask me a follow up question by @ mentioning me again :speech_balloon: ----------------------
