Bulk labeling contacts only labels some not all

Hi, I need some help. I am trying to teach myself to code, but I have trouble with async functions.

I am trying to query our custom database and label all who meet the criteria. Query results length is 155, but only 100 or so get labeled. I think the function needs more time, but I don’t get how to do it.

front end code:
import wixData from ‘wix-data’ ;
import { LabelforMailing } from ‘backend/contacts.jsw’ ;

async function filterResults ( low , high ) {

if ( $w ( “#dropdown8” ). value ) {

**await**  wixData . query ( "Membership" ) 
    . eq ( "memberStatus" ,  $w ( "#dropdown8" ). value ) 
    . limit ( 1000 )  
    . find () 
    . then ( ( results ) => { 
**if** ( results . items . length  >  0 ) { 
  **let**  items  =  results . items ; 

  console . log ( results . items . length ); 
   
  
  **for**  ( **let**  i  =  0 ;  i  <  results . items . length ;  i ++) { 
    **let**  item  =  results . items [ i ]; 
    **let**  mailingId  =  item . title ; 

console . log ( mailingId ); 

LabelforMailing ( mailingId )
}
}
})
}
}

export function button48_click ( event ) {
filterResults ()
}

backend code:

import { contacts } from ‘wix-crm-backend’ ;

export async function LabelforMailing ( mailingId ) {
const contactId = mailingId ;
const labelKey = [
“custom.todays-mailing”
];
const options = {
suppressAuth : true
};
await contacts . labelContact ( contactId , labelKey , options )
. then (( labeledContact ) => {
return labeledContact ;
})
. catch (( error ) => {
console . error ( error );
});
}

console logs all 155 items by id. So when the backend is called, not all of the ids are passed on??
