I have made a Azure function (http-trigger) and deployed it in the portal using Visual Studio 2019.
The function works fine and I now will add a binding to my CosmosDB. I navigate to my function and click on “Integration”. Now I see the trigger, the function and input and output bindings.
I should be able to add a new input binding here. But I have no “add”button. What am I doing wrong?
You cannot add it on the Portal because you are authoring the Function on VS, your screenshot shows that this is a Pre-compiled Function (basically it is compiling in your machine and publishing the DLLs), so you cannot alter it because it's already compiled.
The only scenario where you can add or remove Inputs or Outputs on the Portal is when the Function was created and authored (code written) in the Portal or on csx files, meaning you can actually edit the source code in the Portal itself.
