Declaration of Smalot\Cups\Transport\Client::sendRequest(Psr\Http\Message\RequestInterface $request) must be compatible with Psr\Http\Client\ClientInterface::sendRequest(Psr\Http\Message\RequestInterface $request): Psr\Http\Message\ResponseInterface

After update from 0.4 to 0.5 I get this error:

"Declaration of Smalot\Cups\Transport\Client::sendRequest(Psr\Http\Message\RequestInterface $request) must be compatible with Psr\Http\Client\ClientInterface::sendRequest(Psr\Http\Message\RequestInterface $request): Psr\Http\Message\ResponseInterface"

This is because of version constraints of dependencies has been removed

  - Upgrading php-http/promise (v1.0.0 => 1.1.0): Extracting archive
  - Upgrading php-http/httplug (v1.1.0 => 2.2.0): Extracting archive

  - Upgrading smalot/cups-ipp (v0.4 => v0.5): Extracting archive

php-http/httplug ^2.0 introduces a new interface for ClientInterface

Is there any fix to this?

Here is some temporary workaround:

in Transport/Client.php
add: use Psr\Http\Client\ClientInterface;
add: use Psr\Http\Message\ResponseInterface;

del: class Client implements HttpClient
add: class Client implements ClientInterface

del: public function sendRequest(RequestInterface $request)
add: public function sendRequest(RequestInterface $request): ResponseInterface

in Manager/ManagerAbstract.php

del: use Http\Client\HttpClient;
add: use Psr\Http\Client\ClientInterface;

del: * @var \Http\Client\HttpClient
add: * @var \use Psr\Http\Client\ClientInterface;

del:  public function __construct(Builder $builder, HttpClient $client, ResponseParser $responseParser)
add: public function __construct(Builder $builder, ClientInterface $client, ResponseParser $responseParser)

del:      * @param \Http\Client\HttpClient $client
add:      * @param \Psr\Http\Client\ClientInterface $client

That should do the trick. Also I had some hostname issues, so in Client.php I made this:
$host = 'https://<domain>:631;

Maybe a fork of this project ? The author has not maintained the project for 2 years

I can advise using: JulianOsorio078/cups-ipp

If you need guzzlehttp/psr7 2.4.3 then you have to find another solution.
