How do you read the data?

Could you please show it?

26

By the way I am reading the prebuilt location metadata.

@VIGHNESHNS2008 please edit your post, using the pencil icon at the bottom, and add triple backticks at the beginning and end of your code so that it displays correctly.
Triple backticks look like this:
```

Pete.

So you read the first param lon, in order to read the next one you need to use param[2].asStr(). Right only lon/lat is supported. It was done for one of the clients. I’ll check if can attach more data.

32

Will try

33

I am able to read latitude and longitude. I tried reading param1,2,3,4,5,6,7,8.
Two have values. Other’s blank. Yhere are other values country state zip
