Hello experts,

I have a question about Cognite Functions.

 

I know there’s a limit on the size of the input data, as discussed here : Cognite Hub and documented there : Cloud provider limitations - Cognite Docs

 

But is there a limit on the size of the function’s output?

 

I have one that works perfectly fine but crashes without any explicit error message when handling a large output payload (>500 KB). I’m on Azure provider.

Is there any information on this?

 

Thank you,

Best regards,

Pierre Rambourg

 

edit : the initial error was on my side, but i’m still interested for output limits !

​@RAMBOURG Pierre Yes, there is indeed a limit on the size of a Cognite Function's output. As I recall, the response size limit is 1 MB for function calls.

You can check the exact limits configured for your project by calling the Functions limits API endpoint. The responseSizeMb field will show the applicable limit.

      ​@Mithila Jayalath  I missed the obvious: checking the API documentation :) Thanks a lot !
