"Notice: Undefined index:" error

Hello!     I'm getting this message when trying to view the page.

Notice: Undefined index: IdInstaller in C: \ wamp64 \ www \ solus \ summary_dia.php on line 378

On line 378 I have the following structure. 

375- $sqlEntregasRetornos_res = $conn->prepare($sqlEntregasRetornos);
376- $sqlEntregasRetornos_res->execute();        
377- $lstEntregasRet = $sqlEntregasRetornos_res>fetchAll(PDO::FETCH_ASSOC);
378- $teste = $lstEntregasRet["IdEntregador"];                      
379- var_dump($lstEntregasRet);

// Na linha 378 também tentei extrair da seguinte forma     
   $lstEntregasRet["IdEntregador"];
  

Displaying the contents of the variable is displaying the information correctly.   As below: 

array (size=8)
  0 => 
    array (size=3)
      'IdEntregador' => string '4' (length=1)
      'QtdeRetorno' => string '4' (length=1)
      'Descricao' => string 'RETORNO' (length=7)
  1 => 
    array (size=3)
      'IdEntregador' => string '20' (length=2)
      'QtdeRetorno' => string '1' (length=1)
      'Descricao' => string 'RETORNO' (length=7)

The $ test variable returns null C: \ wamp64 \ www \ solus \ summary_dia.php: 381: null

I honestly do not know what I might be doing wrong, I have 4 other structures that are working perfectly, I checked all the information and I do not know what's wrong. I had another situation similar to this, but I solved it in 2 min, the problem was in the foreach structure, which is not the case now.

Your dump shows clearly what the problem is. Is that lstEntregasRet is receiving ALL rows from the query.

You have to do a foreach of lstEntregasRet and get every subarray, 

foreach ($lstEntregasRet as $linha)
{
    $IdEntregador = $linha['IdEntregador'];
    ...
}
