This method seems to be duplicated in your project.

        if (\is_string($mutateAndGetPayload) && 0 === \strpos($mutateAndGetPayload, '@=')) {
            $cleanMutateAndGetPayload = \substr($mutateAndGetPayload, 2);
        } else {
            $cleanMutateAndGetPayload = \json_encode($mutateAndGetPayload);
        }

        return $cleanMutateAndGetPayload;
    }
