Could not set property 'id' of 'class com.rstech.base.qms.client.model.entity.RsShipRecordDetail' with value

This error message indicates that there was an attempt to set the value of the 'id' property of a 'RsShipRecordDetail' object, but the value provided was not valid or could not be processed.

There could be several reasons why this error occurred, including:

- The value provided for the 'id' property was null or empty.
- The data type of the value provided for the 'id' property was incorrect.
- The 'id' property is read-only or has some other restriction that prevents it from being set.
- There was an issue with the database or persistence layer that prevented the 'id' property from being set.

To resolve this error, you may need to review the code that is attempting to set the 'id' property and verify that the value being provided is valid and in the correct format. You may also need to check the documentation or source code for the 'RsShipRecordDetail' class to determine if there are any restrictions on setting the 'id' property. Additionally, you may need to investigate any database or persistence layer issues that could be preventing the 'id' property from being set correctly.
