[Question, potentially a bug] How to debug requests when creating a server

[BelleNottelling]

Hi there, I'd appreciate some assistance on the following error that's produced by the SDK:

[09-Feb-2024 07:13:20 UTC] HTTP Error
~~~~~~~~~~
The remote server returned a "400 Bad Request" error for the following transaction:
 
Request
~~~~~~~
POST /compute/v2.1/servers HTTP/1.1
User-Agent: GuzzleHttp/7
Content-Type: application/json
Host: something
 
Response
~~~~~~~~
HTTP/1.1 400 Bad Request
Date: Fri, 09 Feb 2024 07:13:20 GMT
Server: Apache/2.4.52 (Ubuntu)

This error is produced with code as follows:

// Creates a new user on the OpenStack server and then establishes a new OpenStack connection instance using the new user's credentials.
$OpenStack = $this->authenticateAsClient();

// Now create a new network for the server to be attached to
$network = $OpenStack->networkingV2()->createNetwork([
 'name' => "Some name",
 'adminStateUp' => true,
]);

// Finally create the server
$server = $OpenStack->computeV2()->createServer([
 'name' => "Some name",
 'imageId' => "The image ID",
 'flavorId' => "The flavor ID",
 'networks' => [
 ['uuid' => $network->id]
 ],
]);

I am fairly new to OpenStack and I am working on a project with it, so I apologize if there's something I am blaitantly doing wrong here, but the logged message isn't particularly clear on what the problem is & searching "debug" on the docs returns no results.

Thanks!

Hello,

1. you can get full request/response by passing additional options to the Openstack object. Like we do for debugging integration tests:

$options = [
 'debugLog' => true,
 'logger' => new \OpenStack\Sample\DefaultLogger(),
 'messageFormatter' => new \GuzzleHttp\MessageFormatter(\GuzzleHttp\MessageFormatter::DEBUG),
 // .. auth options ...
];
$openstack = new OpenStack($options);

2. You can find official API documentation for this endpoint at https://docs.openstack.org/api-ref/compute/#create-server

What php memory limit do you have?
It should output the full request/response body in the error by default:

openstack/src/Common/Error/Builder.php

Line 99 in d823be3

if (ini_get('memory_limit') < 0 || $message->getBody()->getSize() < ini_get('memory_limit')){
