Hi,
 
I am getting the below error while browsing ODATA.
Does anyone know what can be the issue ?

    Can you share with us more details?
     
    What is the entity you are trying to call?
    Is it get or post?
    Also what's the URL u are calling and if there is body what is the body?
     
    Thanks,
    Layan Jweihan

    Hi,
    Required parameters or attributes may be missing, causing null values to be passed where they should not be. You may need to debug and check your code logic.
    Best Regards,

    Hi, the error message indicates that a value is null, you can check the code where the error occurs and ensure that all required values are properly initialized and assigned before being used.

    Hi,

    this is just a URL/data that gives me this error.
    Basically it should give me list of all odata entities.
     
    thanks,

    Hi VM,

    maybe it's better if you show us a screenshot
    Make sure your url is correct and that you're getting your token correctly if you are using postman.

    i just tried it and it works perfectly fine


    Also from browser it's working fine, maybe make sure your user is a sys admin as well just in case

    Thanks,

    Hi,
     
    It is a simple URL which usually shows the odata entities.
    I have below version
    Installed product version : 10.0.38 (10.0.1777.95)
    Installed platform version : Update62 (7.0.7120.100)
    URL is the std url .
    I am not sure what the issue is here.
    Even in case there is an issue with any of the entity then it should atleast show which one is causing this error.
    Thanks,

    Hi,

    Can you try to call the URL from postman and let us know if you are facing the same issue?
