Hi.

We're currently developing a service for fetching realtime currency from a online broker.

The result is a JSON, like this:

[
{
"symbol": "USD/NOK",
"timestamp": "2022-03-22T06:58:35.690285Z",
"rate": 1.566015
},
{
"symbol": "SEK/NOK",
"timestamp": "2022-03-22T06:58:35.690370Z",
"rate": 1.566015
}
]

My datastore is like this:

When i run ln_rest.retrieve(ln_ds,ls_url), I get error -16 - "The JSON is not a plain JSON with two-level structure".

However, the respons looks exactly like one of the examples in the documentation (The section called "Plain JSON"), and is indeed a two-level JSON.

Brackets and curly braces indicates an array of two objects as far as I know.

So what's the reason why my restclient.retrieve fails?

 

Note: I works just fine if I collect the responsebody and parse it using the JSONParser object.

 

Update: it seems that restclient.retrieve() does not support other than string, integer, boolean or null:

"A plain JSON can only contain elements of the following 4 data types: integer, string, boolean, and null."

So I guess the decimal is causing the error message?

If so, that's a really big limit which has to be sorted.

 

Using PB 2019R3.
