When using useList with @refinedev/nestjs-query

Hi @Justin. I'm kapa.ai, your friendly support bot. I will try to answer your question by searching through the knowledge base. :wave:
----------------------
Based on the information provided in the knowledge sources, it seems like you're encountering an error when using the
useList hook with @refinedev/nestjs-query. However, the specific error you're encountering isn't directly addressed in the provided sources.
The error message suggests that there's an attempt to read the 'length' property of an undefined object in your code. This typically happens when you're trying to access a property or method on an object that hasn't been initialized yet.
Without more specific information about your implementation, it's hard to provide a definitive solution. However, you might want to check the data you're passing to useList and ensure it's correctly formatted and not undefined.
For more information on how to use useList, you can refer to the Refine documentation (https://refine.dev/docs/data/hooks/use-list/).
If the problem persists, it might be helpful to open an issue on the Refine GitHub page (https://github.com/refinedev/refine/issues) to get help from the community.

@kapa.ai Is there a debug mode so it logs everything to trace the problem
Let me check the knowledge base for you. One moment! :books:
----------------------
Yes, Refine provides its own devtools that you can use to manage your Refine packages, get insights about your queries and mutations, and explore additional information about your app's components, their interactions, and their impact on data flow. This can be very helpful for debugging and tracing problems in your application.
You can dive deeper into your application inner workings with Refine's devtools. Gain invaluable insights into your queries and mutations, allowing you to fine-tune your data operations for optimal performance. The X-Ray feature offers a unique perspective, enabling you to explore additional information about your app's components, their interactions, and their impact on data flow.
For more information on how to use Refine's devtools, you can refer to the Refine devtools documentation (https://github.com/refinedev/refine/tree/master/packages/devtools).
If you want to prevent the devtools-server from running, you can use the parameter
npm run refine dev -- --devtools=false as mentioned in one of the GitHub discussions (https://github.com/refinedev/refine/issues/5211).
Please note that the specific logging level (e.g., debug, trace, info, warn, error) might depend on your application's configuration or the specific logger you're using.
