TypeValue error while executing query entity

You try to compare the field id to a string. To make that work, change line 2 to list of numbers like

local!panelId: {1,2}

Hi, your local!panelId variable is currently defined as text, it appears you would like to define it as a list of integer such as {1,2}.  Try this code instead:

a!localVariables(
  local!pandelId: {1,2},
  a!queryEntity(
    entity:cons!IM_INTERVIEW_PANEL_DSE_POINTER,
    query: a!query(
      selection: a!querySelection(
        columns: {
          a!queryColumn(
            field: "name"
          )
        }
      ),
      filter: a!queryFilter(
        field:"id",
        operator:"in",
        value: local!panelId
      ),
      paginginfo: a!pagingInfo(
        startIndex: 1,
        batchSize: -1
      )
    )
  ).data.name
)

Beat me by a nanosecond :) 

Actually I got the value - "1; 2" from CDT field. For testing, I have used same value in local variable. 

Is the CDT field a single value, or multiple, and which data type?  Can you confirm that the "id" field is a single integer field?

CDT field is single value but it store value in this format - "1; 2". 

"id" field is a single integer field

As you are storing multiple integer values in a single text field, you can use a combination of split() and tointeger() to format correctly for the query:

a!localVariables(
  local!pandelId: a!forEach(
    items: split(
      "1; 2", /* replace with a call to your CDT field */
      ";"
    ),
    expression: tointeger(fv!item)
  ),
  a!queryEntity(
    entity:cons!IM_INTERVIEW_PANEL_DSE_POINTER,
    query: a!query(
      selection: a!querySelection(
        columns: {
          a!queryColumn(
            field: "name"
          )
        }
      ),
      filter: a!queryFilter(
        field:"id",
        operator:"in",
        value: local!panelId
      ),
      paginginfo: a!pagingInfo(
        startIndex: 1,
        batchSize: -1
      )
    )
  ).data.name
)

Solution is working. Thank you so much. 

Great!

I would like to know how the CDT looks like. I mean the one from which you get the "1; 2" string. Appian displays a list of numbers in expression designer just like this. Please give a bit more details. I want to make sure to not guide you into a wrong direction.
