What kind of animal is a DecisionOutputRestrictionLookup?

Hi,

I have a portal in with an interface containing a grid.

The grid is populated through an integration calling an integration to a web API that execute a queryRecordType. The integration has one rule input, pagingInfo, that gets value from grid pagingSaveInto property. WebAPI receives a couple of query parameters, startIndex and batchSize, used to create a new pagingInfo object for the queryRecordType function.

It works smoothly when I test the interface form Designer, but once it is published in the Portal I get one of these errors whenever I try to get the grid interface. Sometimes I get error 1 and sometimes error 2 (clicking on the same button, it's curious), I cant find a pattern out of it so far.

Errors:

1) HTTP Code 500. Expression evaluation error [evaluation ID = BNS4C] in rule 'ct_portal_publishedtexts' at function a!gridField [line 50]: A grid component [label="null"] has an invalid value for "data". "data" must be sourced from a Record Type, a query, a list of Dictionary, a list of CDT, or a data subset. Received: DecisionOutputRestrictionLookup

2) HTTP Code 500. Could not decrypt bindings.

Some code snippets:

2) Portal home interface

a!localVariables(
  local!newLine: char(10) & char(10),
  local!name,
  local!email,
  local!aviso,
  local!screen: "main",
  
  {
    a!match(
      value: local!screen,
      
      equals: "publishedTexts",
      then: rule!CT_Portal_PublishedTexts(screen: local!screen),
      
      default: a!columnsLayout(
        columns: {
          a!columnLayout(),
          a!columnLayout(
            contents: {
              a!buttonLayout(
                secondaryButtons: {
                  a!buttonWidget(
                    label: "Ver textos publicados",
                    validate: false,
                    value: "publishedTexts",
                    saveInto: local!screen
                  )
                }
              )
            }
          )
        }
      )
    )
  }
)

1) Interface CT_Portal_PublishedTexts

a!localVariables(
  local!pagingInfo: a!pagingInfo(1,10),
  local!data: cast(
    typeof(a!dataSubset(startIndex: 1, batchSize: 1, data:{1,2})),
    rule!CT_GetPublishedTexts(pagingInfo: local!pagingInfo).result.body,
  ),
  
  local!text,
  
  {
    a!richTextDisplayField(
      value: {
        a!richTextIcon(
          icon: "arrow-left",
          link: a!dynamicLink(
            saveInto: if(
              isnull(local!text),
              a!save(ri!screen,"main"),
              a!save(local!text,null)
            )
          ),
          linkStyle: "STANDALONE"
        )
      }
    ),

    if(
      isnull(local!text),
      {
        a!gridField(
          emptyGridMessage: "No hay textos para mostrar",
          data: local!data,
          columns: {...},
          pagingSaveInto: local!pagingInfo,
          borderStyle: "LIGHT",
          shadeAlternateRows: false
        )
      },
      {
        a!sectionLayout(
          contents: {},
        )
      }
    )
  }
)

2) Web API

a!localVariables(
  local!records: a!queryRecordType(
    recordType: 'recordType!{d74c7061-f193-4922-85bb-1b8b85db7b97}CT Text',
    filters: a!queryFilter('recordType!{d74c7061-f193-4922-85bb-1b8b85db7b97}CT Text.fields.{2f953619-9bfc-4cde-905f-2ca23df99c29}datePublished',"not null"),
    pagingInfo: a!pagingInfo(
      startIndex: http!request.queryParameters.startIndex,
      batchSize: http!request.queryParameters.batchSize,
      sort: a!sortInfo('recordType!{d74c7061-f193-4922-85bb-1b8b85db7b97}CT Text.fields.{2f953619-9bfc-4cde-905f-2ca23df99c29}datePublished',false)
    ),
    fetchTotalCount: true
  ),
  a!httpResponse(
    headers: {
      a!httpHeader(name: "Content-Type", value: "application/json")
    },
    body: a!toJson(local!records)
  )
)

Just in case it is not clear enough, my intention is to show in a portal a readonly grid that takes data from a record (through a web api).

Any help will be appreciated

Thanks in advance
