Failed to resolve type using symfony deserializer

[Bleksak]

                $message = $this->serializer->deserialize(
                    $buffer,
                    SubmissionProducerMessage::class,
                    'json',
                );

Should be of type SubmissionProducerMessage, but instead it's of type mixed.

This is the definition of the deserialize method:

    /**
     * Deserializes data into the given type.
     *
     * @template TObject of object
     * @template TType of string|class-string<TObject>
     *
     * @param TType                $type
     * @param array<string, mixed> $context
     *
     * @phpstan-return ($type is class-string<TObject> ? TObject : mixed)
     *
     * @psalm-return (TType is class-string<TObject> ? TObject : mixed)
     *
     * @throws NotNormalizableValueException Occurs when a value cannot be denormalized
     * @throws UnexpectedValueException      Occurs when a value cannot be decoded
     * @throws ExceptionInterface            Occurs for all the other cases of serialization-related errors
     */
    public function deserialize(mixed $data, string $type, string $format, array $context = []): mixed;

I think wee only handle @return but assume PHPStan style.

@Bleksak could you please check if this is still an issue. It should have been fixed in d14998d

[Bleksak]

it's now SubmissionProducerMessage|mixed, not sure if that matters anyhow, but it should only be SubmissionProducerMessage.

I think it happened because * @psalm-return (TType is class-string<TObject> ? TObject : mixed) phpantom doesn't correctly run the type coercion on TType so it assumes both cases can be correct

Should be fixed now: bf0ac3a
