businessId = 1002exchange data with server error

As an AI language model, I don't have access to your server or the specific details of your error. However, here are some general troubleshooting steps you can try:

1. Check your network connection: Make sure you have a stable internet connection and that your device is connected to the network.

2. Verify the server status: Check the status of the server to ensure that it is functioning properly. If the server is down or experiencing issues, it may be the cause of the error.

3. Review your code: Check your code for errors and make sure that you are sending the correct data to the server. Double-check that the businessId is correct and in the correct format.

4. Contact server support: If you have tried the above steps and the error persists, contact the server support team for assistance. They may be able to provide more specific guidance on how to resolve the issue.
