Code:

a!forEach(pv!addedResearchItems_cdt,
 if(
and(rule!APN_isBlank(index(fv!item,"id",{})),rule!APN_isBlank(fv!item.url)),

cast('type!{urn:com:appian:types:gngp}GNGP_RESEARCH_ITEM',updatecdt(fv!item,{file_name:
if(not(isnull(fv!item.file_name)),
fv!item.file_name,
if(not(isnull(fv!item.document_id)),document(todocument(fv!item.document_id), "name") & "." & document(todocument(fv!item.document_id), "extension"),{})
   )})),
 
  fv!item
))

Getting below error:

(Expression evaluation error at function a!forEach: Error in a!forEach() expression during iteration 1: Expression evaluation error at function 'updatecdt' [line 5]: Length of input arrays must equal length of CDT/Dictionary array) (Data Outputs)

Please help to rectify the above error as what code changes needs to be done

    Try this

    a!forEach(
  pv!addedResearchItems_cdt,
  if(
    and(
      rule!APN_isBlank(index(fv!item, "id", {})),
      rule!APN_isBlank(fv!item.url)
    ),
    cast(
      'type!{urn:com:appian:types:gngp}GNGP_RESEARCH_ITEM',
      a!update(
        fv!item,
        { "file_name" },
        {
          if(
            not(isnull(fv!item.file_name)),
            fv!item.file_name,
            if(
              not(isnull(fv!item.document_id)),
              document(todocument(fv!item.document_id), "name") & "." & document(
                todocument(fv!item.document_id),
                "extension"
              ),
              {}
            )
          )
        }
      )
    ),
    fv!item
  )
)

    Make sure code returns a value to update or use a null check before
    if(
    not(isnull(fv!item.file_name)),
    fv!item.file_name,
    if(
    not(isnull(fv!item.document_id)),
    document(todocument(fv!item.document_id), "name") & "." & document(
    todocument(fv!item.document_id),
    "extension"
    ),
    {}
    )
    )
