Failure to parse incoming JSON

Hello everyone,

I am trying to parse a json event in geoevent 10.7.1 using a field mapper, in order to flatten the structure and be able to access the indexed objects, yet i keep failling.

Here's how my field mpper looks like :

So, instead of getting the simple structure as defined in my target geoevent definition, i keep getting the initial structure.

Any ideas please ?

Take your source data and run it through https://jsonlint.com/. You will see that you have an array inside the data object but the data object is not an array.

So data.slots[0].id looks like it might make more sense... But I also have issues when working with arrays inside GeoEvent so let us know..
