Unable to Store data in Appian DB

Hi team,

I am trying to save data in Appian db. I am using the records to fetch the data. I have created a record action for data creation too but that is not working fine.

When I click on the above create suite option, it opens up a form like below:-

The expression rule for the above form is given below- [At line 16th, If I put value: local!UUID, it does not works but if I put value: ri!record.uuid, I am able to save the data in db. But I want to save a auto generated UUID and hence used local variable]

a!localVariables(

  local!UUID: rule!BTUA_GenerateUUID_Expression(),
  a!formLayout(
    label: "Create Suite",
    contents: {
      a!columnsLayout(
        columns: {
          a!columnLayout(
            contents: {
              a!textField(
                readOnly:  true,
                label: "Uuid",
                labelPosition: "ABOVE",
                required: true,
                value: local!UUID,
                saveInto: ri!record.uuid,
                characterLimit: 300,
                
              )
            }
          ),
          a!columnLayout(
            contents: {
              a!textField(
                label: "Suite Name",
                labelPosition: "ABOVE",
                required: false,
                value: ri!record.suitename,
                saveInto: ri!record.suitename
              )
            }
          )
        }
      )
    },
    buttons: a!buttonLayout(
      primaryButtons: {
        a!buttonWidget(
          label: "Submit",
          submit: true,
          validate: true,
          style: "PRIMARY"
        )
      },
      secondaryButtons: {
        a!buttonWidget(
          label: "Cancel",
          value: true,
          saveInto: ri!cancel,
          submit: true,
          style: "NORMAL",
          validate: false
        )
      }
    )
  )
)

Now when I am providing some text value to suite name and hitting on submit button. Its not getting saved and giving me following error:

Also in the table, the value of UUID is not getting saved due to which the issue is happening with the sync

Could u pls help in fixing this ?
