Retrieve all properties from a thing

Hello,

I have the following challenge: I want to extract all properties, which are available/present on a certain thing, to an info table. I used the following code to achieve this:

var result = Things[ThingName].GetPropertyDefinitions({
category: undefined /* STRING */,
type: undefined /* BASETYPENAME */,
dataShape: undefined /* DATASHAPENAME */
});

My problem is, that it gets me only 999 entries but my thing has more that 999 properties.

Is there a way to get more/all entries? maxItems did not work.

Hi PaiChung,

thank you for the feedback. All properties of the relevant Thing are grouped on various ThingShapes.

I solved the issue in the following way:

getImplementedShapes > InfoTable with all Shapes

Iterate through Shapes InfoTable and use > GetInstancePropertyDefinitions > retrieve all properties and write them to an Property InfoTable.

That seems like way too many properties on a Thing, but perhaps you can group those into ThingShapes and retrieve the ThingShapes and then the properties so there are less than 999 per ThingShape.
