dataHub | ReactJS frontend web application for browsing | Frontend Framework library

I am hosting a dotnet 3.1 WebApi with SignalR on IIS 8 with WebSocket Protocol enabled on the server. The hosted API application works just fine for the first few minutes but stops working after a while and doesn't respond to any requests.

Client-end is in Angular 11, which works as it should be. but when this happens, the client-side takes a long time to finish the API request.

And have to restart the application then again it works for few minutes.

IIS log shows this error

System.InvalidOperationException: The 'InvokeCoreAsync' method cannot be called if the connection is not active

Searched for this error but nothing is working till now.

Previously I've reported it into kafkacat tracker but the issue has been closed as related to cyrus-sasl/krb5.

Help...

I have been looking into OData for .NETCORE for the first time but can't seem to achieve something quite simple.

I have created an unbound function which returns a string and accepts a string parameter, I have read multiple docs and copied exactly what they did there (except, I replaced the int parameter for a string).

So I ended up with the following setup (I am using .NET 5 / API):

I have a simple application that queries a remote URL for a city code.

I'm working on a Gradle (Groovy, not Kotlin) library using a bunch of external libraries, and we have a case where we want to implement double-inheritance in our code off of a custom Task provided by an external library. (For reference, that library is specifically the MarkLogic DataHub, and we're extending RunFlowTask, but I've generalized a bit for this example. There are a few restrictions that introduces, but I'm fairly certain all of them can be worked around.)

What I want is the following:

ClassA.gradle

I am using material UI to list dropdown value I have a hub,Country and account dropdown fields i want to set the first value of the array object to select initial value selected.

data file:

I am using the latest versions of Marklogic datahub and MarkLogic Server.

• Data Hub 5.4.1 QuickStart
• MarkLogic Server Version 10.0-6.2

In MarkLogic Datahub, I have created a flow for a data source.

Here the data source is reading data from csv files.

I have created an entity and I am able to do the Ingestion and Mapping.

After executing the Ingestion and Mapping steps, I have observed that the triples do not get generated in the mapping output file.

Am I missing some steps here which is required for the data hub to generate the triples in the Mapping output file?

I kindly request you to help me in this regard.

Thank You.
