[Flow] Validation triggered when trying to show object in rest controller

[Carsten Bleicker]

Running into the same and solved it by override the action invoking the validation:
	/**
	 * Invokes only on writing request methods (POST/PUT/PATCH)
	 *
	 * @return void
	 */
	protected function initializeActionMethodValidators() {
		if ($this->request->getHttpRequest()->getMethod() === 'POST' || $this->request->getHttpRequest()->getMethod() === 'PUT' || $this->request->getHttpRequest()->getMethod() === 'PATCH') {
			parent::initializeActionMethodValidators();
		}
	}

Unfortunatly it doesnt give me any further information on why the validation fails. I already looked into the logs, with no success in finding what is going wrong here.
