It seems like \Spatie\SlashCommand\Request::createFromIlluminateRequest($request) of type object<self> is incompatible with the declared type object<Spatie\SlashCommand\Request> of property $request.

        $this->config = collect($config->get('laravel-slack-slash-command'));
    }

                $handler->validate();
            }
            $response = $handler->handle($this->request);
        } catch (SlackSlashCommandException $exception) {

        } catch (Exception $exception) {
            $response = $this->convertToResponse($exception);
        }

        return $response->getIlluminateResponse();
    }

            throw InvalidRequest::tokenNotFound();
        }

        $validTokens = $this->config->get('token');

        if (! is_array($validTokens)) {
            $validTokens = [$validTokens];
        }

        if (! in_array($this->request->get('token'), $validTokens)) {
            throw InvalidRequest::invalidToken($this->request->get('token'));

    protected function determineHandler()
    {
        $handler = collect($this->config->get('handlers'))
            ->map(function (string $handlerClassName) {

            ->filter(function (HandlesSlashCommand $handler) {
                return $handler->canHandle($this->request);

It seems like you code against a concrete implementation and not the interface Spatie\SlashCommand\HandlesSlashCommand as the method canHandle() does only exist in the following implementations of said interface: Spatie\SlashCommand\Handlers\BaseHandler, Spatie\SlashCommand\Handlers\CatchAll, Spatie\SlashCommand\Handlers\Help, Spatie\SlashCommand\Handlers\SignatureHandler.

            })
            ->first();

        if (! $handler) {
            throw RequestCouldNotBeHandled::noHandlerFound($this->request);

    protected function convertToResponse(Exception $exception) : Response

        $message = config('app.debug') ? (string) $exception : 'Whoops, something went wrong...';

        $exception = new SlackSlashCommandException(
            $message,
            $exception->getCode(),
            $exception
        );

        $response = $exception->getResponse($this->request);

        return $response;
