When I switch from APP_ENV=dev to prod, I get an empty response with undefine data from my controller JsonResponse.

I am on a track to fix this but need help:

When using postman, the request to my controller give me 2 things:

1:

=> it' what I can read when doing console.log(response);
2:
{"dataClubInfo":{"nomClub":"......}} with my preciouse data !
=> it's the response I get from my controller return new JsonResponse(["dataClubInfo"=>$retourClubTab]);

To resume on dev I have an objet with my data ( {dataClubInfo: {…}} ) and in prod I get no data but :<script> Sfdump = window.Sfdump )

Would someone be able to help me ?
