Conversion of Resource (stream) in php bringing unexpected results

Question

Environments

• Local
  • AS: Linux Mint 19.3;
  • Bench: Postgresql 12.2 (Ubuntu 12.2-2.pgdg18.04+1);
  • PHP: 7.3.17-1+ubuntu18.04.1+deb.sury.org+1.
• Amazon
  • AS: Amazon Linux 2018 V1 - Beanstalk V2.9.3;
  • Bank (RDS): Postgresql 12.2 on x86_64-pc-linux-gnu;
  • PHP: 7.3.15

I have a queue table that has a field like bytea, it stores various information on json, when retrieved in PHP it is identified as a Resource (stream)...

In the local environment, the conversion using stream_get_contents, works normally... but in AWS environment (machine created through Beanstalk + Pipeline) no, example:

Local

// Antes da conversão
var_dump(stream_get_meta_data($r['job']));

// Resultado
array (size=7)
  'timed_out' => boolean false
  'blocked' => boolean true
  'eof' => boolean false
  'stream_type' => string 'MEMORY' (length=6)
  'mode' => string 'w+b' (length=3)
  'unread_bytes' => int 0
  'seekable' => boolean true

// Conversão
$r['job'] = stream_get_contents($r['job']);

// Resultado
var_dump($r['job']);
string(532) '{"class":"common\jobs\EmailJob","from": ........'

AWS

// Antes da conversão
var_dump(stream_get_meta_data($r['job']));

// Resultado
array (size=7)
  'timed_out' => boolean false
  'blocked' => boolean true
  'eof' => boolean false
  'stream_type' => string 'MEMORY' (length=6)
  'mode' => string 'w+b' (length=3)
  'unread_bytes' => int 0
  'seekable' => boolean true

// Conversão
$r['job'] = stream_get_contents($r['job']);

// Resultado
var_dump($r['job']);
string(1077) "x7b22636c617373223a22636f6d6d6f6e5c5c6a6f62735c5c456d61696c4a6f62222c2266726f6d223a7b2272616661656c2e7769746....."

The code was tested locally by other developers, including in Windows environment, and this problem did not occur... What may be causing this conversion divergence on the server?
