Gson assigns null values when there are values in the json input - json

Question

I get null for objects when there is a value in the json. It happens with the first object.
Here is the json:
{
"quakeml": {
"eventParameters": {
"event": [
{
"description": [
{
"text": "S0959a",
"type": "earthquake name"
}
],
"origin": {
"longitude": {
"value": 135.6234
},
"latitude": {
"value": 4.5024
},
"distance": {
"value": 32.5
}
},
"magnitude": [
{
"mag": {
"value": 3.2
},
"type": "MbS",
"originID": "smi:insight.mqs/origin/20220623-123048/ebd6d417"
},
{
"mag": {
"value": 3.2
},
"type": "MbP",
"originID": "smi:insight.mqs/origin/20220623-123048/ebd6d417"
},
{
"mag": {
"value": 3,
"lowerUncertainty": 0.4,
"upperUncertainty": 0.4
},
"type": "MWspec",
"originID": "smi:insight.mqs/origin/20220623-123048/ebd6d417"
},
{
"mag": {
"value": 3,
"lowerUncertainty": 0.4,
"upperUncertainty": 0.4
},
"type": "MW",
"originID": "smi:insight.mqs/origin/20220623-123048/ebd6d417"
}
]
},
{
"description": [
{
"text": "S0959a",
"type": "earthquake name"
}
],
"origin": {
"longitude": {
"value": 135.6234
},
"latitude": {
"value": 4.5024
},
"distance": {
"value": 32.5
}
},
"magnitude": [
{
"mag": {
"value": 3.2
},
"type": "MbS",
"originID": "smi:insight.mqs/origin/20220623-123048/ebd6d417"
},
{
"mag": {
"value": 3.2
},
"type": "MbP",
"originID": "smi:insight.mqs/origin/20220623-123048/ebd6d417"
},
{
"mag": {
"value": 3,
"lowerUncertainty": 0.4,
"upperUncertainty": 0.4
},
"type": "MWspec",
"originID": "smi:insight.mqs/origin/20220623-123048/ebd6d417"
},
{
"mag": {
"value": 3,
"lowerUncertainty": 0.4,
"upperUncertainty": 0.4
},
"type": "MW",
"originID": "smi:insight.mqs/origin/20220623-123048/ebd6d417"
}
]
}
]
}
}``
}
Here is the gson call:
Example example=null;
example = gson.fromJson(content, Example.class);
I get the error that Example.getQuakeml() is a null. Here is Example class. The class is the standard class created when using a tool that creates java POJOs. That creates standard java beans for gson and also creates the proper annotations for gson.:
import javax.annotation.Generated;
import com.google.gson.annotations.Expose;
import com.google.gson.annotations.SerializedName;
#Generated("jsonschema2pojo")
public class Example {
#SerializedName("quakeml")
#Expose
private Quakeml quakeml;
public Quakeml getQuakeml() {
return quakeml;
}
public void setQuakeml(Quakeml quakeml) {
this.quakeml = quakeml;
}
}
When I use debug I discover that the variable example is null for this standard gson call:
Quakeml quakeml = example.getQuakeml();
I really appreciate the help!
Thanks!!
