Then you need to adapt your validation. It is not the body that is null or not, but your body contains a JSON structure and a field called "value" that is null or not.

Hi Stephan,

Ideally it should go to error handling and should give "404- Document Not Found" if no document is sent.

But if you see the response it is generating a document by itself and giving as : "Response Body": "Upload Successful: 25222 - Untitled document from web API.txt"

Need to see the body . Null or empty also gives false for empty array .If your body coming as a empty array it will go for true statement in that if condition

Can you post the full HTTP request you send to Appian?

RE: Document Upload- WebAPI

Puru Gope — Tue, 07 Jan 2025 04:39:51 GMT

Yes Stefan Helzle ,

I did try and the result was same. I don't see anywhere documented that Appian will create a document by itself and upload it if no document was passed in the body.

Also, I don't see where "Untitled document from web API.txt" part is being handled in the webAPI.

Yes Stefan Helzle ,

I did try and the result was same. However I just don't see anywhere documented that if we don't send any document, Appian is going to create a document by itself and upload it.

Trying to understand whether it's a bug or it's the way it is handled. Even, I don't see where "Untitled document from web API.txt" is being handled.

Did you consider to use a!isnullorempty() instead of isnull()? This is the more modern approach and manages more of the edge cases.

[quote userid="288631" url="~/discussions/f/integrations/38262/document-upload--webapi/144076"] is not taking the body as empty[/quote]

Empty Array returns false (Documented ) https://docs.appian.com/suite/help/24.4/fnc_informational_isnull.html .

[quote userid="288631" url="~/discussions/f/integrations/38262/document-upload--webapi/144076"] from where "Untitled document from web API.txt" is being handled?[/quote]

And coming to this it's taking true in if statement and trying to creating a Document for Empty values

Thanks ,

I don't see any option to see local!success . However, I did fixed it by checking the size of the request.body.

I am just trying to figure out Appian is not taking the body as empty and from where "Untitled document from web API.txt" is being handled?

In negative scenario what's the value of local!success is it really giving you false?? I doubt that Can you check it once, It went for true statement in if condition that means it's true to start with. So try adding one more condition like checking length of the array etc.,
