  -u [email protected]:test \
  -d companyId=39733 \
  -d className='com.liferay.portal.kernel.model.User' \
  -d tableName='CUSTOM_FIELDS' \
  -d columnName='newAtt' \
  -d classPK=127226 \
  -d data='3'

Current result:
An error like this is obtained:

Column 127220 has type custom.field.int and is not compatible with type custom.field.java.lang.String
