oData not working

Hello,
 
we have a problem with oData in one T2 environment. After the 10.0.42 upgrade and numerous ISV upgrades we are experiencing this error whenever any data entity is accesses via URL or office integration:
 
<Message>An error has occurred.</Message>
<ExceptionMessage>Value cannot be null. Parameter name: enumType</ExceptionMessage>

</Error>
 
 
We have an open Microsoft ticket, but they are not really helpful.
 
To me looks like there is an issue with the definition of at least one data entity where the specified enumType is missing. We have deployed a package created through devops with a build machine. The code
compiles (all models) on our dev box with no errors. 
 
Any ideas ?

    Hi,

    Have you refreshed the entity list after the upgrade?
    Is the DMF connection up and running?

    If yes, can you try exporting a DMF job to Excel to verify if the issue persists?

    Hi,
     
    For data entities in V10.0.42, there are a few suggestions:
    - Do a database synchronization and check if there are any errors on FinTag references. A few FinTag references are causing data entities to break.
    - Also, the error message states that you will need a full compile which means a full build and a database synchronization is required.
     
    A few questions:
    1. Can you provide the data entities list where you are facing such issues?
    2. Which enumtype is it erroring on? Need the enumtype name to provide more insights.

    Hi,
     
    Are you calling a standard entity or a custom one?
     
    Can you please provide us with the url you are calling and with the body if it's a POST
     
    Also are u sure it only happens in T2? So if u call the exact same url in T1, does it work?

    If OData is missing Enum definitions, it does sound like it could be a refresh issue. There is the potential that one or more of your numerous ISV updates for 10.0.42 could contain an issue, but for now run a Data Entity refresh from the Data Management workspace.
     
     
    It refreshes Metadata, so if there are new or modified Enums this may be required.
     
     
    If it doesn't work, you may need to start rolling back some of your ISV updates to find the culprit. Unique labels on Data Entities is often overlooked.
     
     
    Failing that, send your OData request as mentioned by other users and we can help further.

    Please check your data entities and make sure all enum types are specified and exist :
     
    <Message>An error has occurred.</Message>
    <ExceptionMessage>Value cannot be null. Parameter name: enumType</ExceptionMessage>
    <ExceptionType>System.ArgumentNullException</ExceptionType>

    Hi Frank,
     
    Surely that would be picked up at compile-time?
