Data records views facing APNX error when viewing interfaces

I am trying to upgrade appian records to utilize v 21.2 features.

Data source, list, sync has been done up without errors.

However, when I passed in rv!records into the SummaryView interface (old), when I go into the list and click into the appID, i will be faced with this error -

An Error Has Occurred ???APNX-1-4205-046??? (APNX-1-4205-046).

Or will i have to refactor summaryView to utilize dot notations? I kinda tried it but its not really working as well. Do let me know if you require more information?

a!localVariables(
  local!serviceArea: “xxx”,
  rule!SummaryView(
    refAppId: rv!record['recordType!{xxx}Applications Upgrade.fields.{xxx}pid'],
    owner: rv!record['recordType!{xxx}Applications Upgrade.fields.{xxx}owner'],
    assignedTo: rv!record['recordType!{xxx}Applications Upgrade.fields.{xxx}assignedTo'],
    status: rv!record['recordType!{xxx}Applications Upgrade.fields.{xxx}refStatusId'],
    isMyGrantRecord: true(),
    recordType: cons!MGP_CMN_RT_APPLICATIONSUPGRADE,

  )
