Hello, got this issue when trying to return content from API REST

message: "Compile Error: Declaration of JMS\Serializer\JsonSerializationVisitor::startVisitingObject(JMS\Serializer\Metadata\ClassMetadata $metadata, JMS\Serializer\object $data, array $type): void must be compatible with JMS\Serializer\Visitor\SerializationVisitorInterface::startVisitingObject(JMS\Serializer\Metadata\ClassMetadata $metadata, JMS\Serializer\Visitor\object $data, array $type): void"

Trace :

vendor/jms/serializer/src/JsonSerializationVisitor.php

My API works on my local machine but got this issue on my test server. (Both with php 7.2.x)

Any idea ?

the production PHP version and dev version should be the same. If is not so, your composer file might contain libraries that can not run on your production env (as in this case, jms/serialzer v2.0 requires at lease php 7.2 thats why works locally and not on production).

You right ! when i did php -v : it was on 7.2 but with phpinfo(); was on 7.1

I updated php and works fine now 👍

Thank you.

Dear Pauchard Thomas, how did you update ... the same thing happens to me ... in php-v I have 7.2 and in phpinfo () I have 7.1

in localhost

@eilsongithub You might have multiple php instances. Look at this link
