Service Prooph\Psr7Middleware\CommandMiddleware did not to resolve to a Psr\Http\Server\MiddlewareInterface

[manuakasam]

Hey guys,

I've just been following the prooph video tutorial over on youtube. Inside he's using the Psr7Middleware.

While using the most current Expressive default installation I'm running into the issue that the CommandMiddleware cannot be instantiated properly as it does not comform with the most current standard that is Psr\Http\Server\MiddlewareInterface.

Upon further inspection I assume this requires an update of the underlying package webimpress/http-middleware-compatibility as I do not see him handling the case inside the package.

Locally this can be solved by class_alias the CommandMiddleware to have the proper interface and structure but I suppose an update either here or on the side of webimpress should be done. If I am overlooking something please let me know, I'll gladly provide more info or PRs where required :)

as far as I'm aware the webimpress/http-middleware-compatibility is now deprecated. We have update our dependencies to use the now stable releasee of psr/http-message:^1.0.

What does compose show tell us version wise?

I suspect you simply need to upgrade...

I might be looking at the wrong places but current master here suggests otherwise 🤔

https://github.com/prooph/psr7-middleware/blob/master/composer.json#L49 and https://github.com/prooph/psr7-middleware/blob/master/src/CommandMiddleware.php#L22

Aside from that this is my composer output

did you see this https://github.com/prooph/psr7-middleware#deprecated ?

Nope. As I haven't checked that readme by following the tutorial. That's been the whole issue. Thanks again for the guidance :-*
