  Incorrect Data Input: Users may inadvertently input multiple values in a field that is restricted to a single entry.

  Solution:
  
  Check Input Values: Review the input parameters being passed to the function or API. Ensure that only a single value is being provided for the parameter that is causing the error.
  Modify Data Mapping: If the error occurs during data integration, check the mapping configuration to ensure that it correctly handles the data and does not attempt to send multiple values for a single-value parameter.
  Debugging: Use debugging tools or logs to trace the source of the error. This can help identify where the multiple values are being introduced.
