Issue when submitting a form

hello everyone,

I created a form action that allows me to insert records into a record list I created. I have modified some fields in the insert form so that they are automatically filled with automatically calculated values; I noticed that the moment I submit , the inserted record has the said fields empty, would you know how this can happen? I made sure that the data types entered are equal to the type declared in each field of the record list, so I am sure I did not accidentally enter a text type inside an integer :) . For more info I attach the error, and an example code of a modified field :

ERROR:

Problem:  An error occurred in executing an Activity Class.

Details:  Each item within the input "Records" must be a record data type. Received: LBOWI - RegistroFirme.

Recommended Action:  Examine the activity class to correct the error and then resume.

Priority of this problem: High Priority

CODE:

a!localVariables(
              local!value : now(),
              a!dateTimeField(
                label: "Indipendence Sign Date",
                labelPosition: "ABOVE",
                value: local!value ,
                saveInto: ri!record['recordType!{769add8e-6340-4224-9efb-1af6bf33b78b}LBOWI - RegistroFirme.fields.{2a30dfa1-b275-41c8-badd-3cdc7b52feec}indipendenceSignDate'],
                required: false,
                readOnly: true,
                disabled: false
              )
            )
