I created a table in Qlik Sense with dimensions and measures. Also one measure has an expression. Why I can't see the expression on console (another fillds I can see)? How to get the content of the table using Websocket? I want to show the table using only table's ID.
Re: Can I get values from a table via a WebSocket?
I think you made a pasting error (you create a variable called GetLayout and then later stringify a variable GetFullPropertyTree) but that shouldnt really matter.
I always use the Engine-API-Explorer for these kind of things because it is very helpful (/dev-hub/engine-api-explorer):
When looking at the result of GetFullPropertyTree we can see that there is no property named "qMeasureInfo" inside the qHyperCubeDef, only a property called "qMeasures".Inside the individual measure's objects is another property called qDef which in turn contains the expression used for this measure.
To find the correct paths / properties just play around with the engine-api-explorer. You can also check out Qliks enigma.js which should simplify the communication with qlik sense
