It seems like you code against a concrete implementation and not the interface
Bruli\EventBusBundle\CommandBus\CommandInterface as the method getErrorMessage() does only exist in the following implementations of said interface: PhpGitHooks\Module\Compo...ct\Command\ComposerTool , PhpGitHooks\Module\JsonL...ct\Command\JsonLintTool , PhpGitHooks\Module\PhpCs...\Command\PhpCsFixerTool , PhpGitHooks\Module\PhpCs...tract\Command\PhpCsTool , PhpGitHooks\Module\PhpLi...act\Command\PhpLintTool , PhpGitHooks\Module\PhpMd...tract\Command\PhpMdTool , PhpGitHooks\Module\PhpUn...act\Command\PhpUnitTool , PhpGitHooks\Module\PhpUn...\Command\StrictCoverage .
Let’s take a look at an example: interface User
{
/** @return string */
public function getPassword();
}
class MyUser implements User
{
public function getPassword()
{
// return something
}
public function getDisplayName()
{
// return some name.
}
}
class AuthSystem
{
public function authenticate(User $user)
{
$this->logger->info(sprintf('Authenticating %s.', $user->getDisplayName()));
// do something.
}
}
In the above example, the authenticate() method works fine as long as you just pass instances of MyUser. However, if you now also want to pass a different implementation of User which does not have a getDisplayName() method, the code will break. Available Fixes
Note: PHP Analyzer uses reverse abstract interpretation to narrow down the types
inside the if block in such a case.

Change the type-hint for the parameter:
Add an additional type-check:
Add the method to the interface:
