Can't load axios data

[SolimanGit]

Hey i wanted to know how to add features with loader on Vector layers, i think i did it but an error occured :
vue3-openlayers.es.js:17674 Uncaught (in promise) TypeError: feature2.getId is not a function at VectorSource2.addToIndex_ (vue3-openlayers.es.js:17674:23) at VectorSource2.addFeaturesInternal (vue3-openlayers.es.js:17699:16) at VectorSource2.addFeatures (vue3-openlayers.es.js:17689:10) at VectorSource2.loadPointFeatures [as loader_] (Map.vue:238:44)

Here is my function loader for vector layer :
async function loadPointFeatures(){ const response_result = await axios.get('http://127.0.0.1:8000/stations'); if (response_result) { console.log(response_result) console.log(geometryPoint.value.values_.source) geometryPoint.value.values_.source.addFeatures(response_result.data[0].features); } }

Weird enough the error is on the second feature, here is the features :

As you can see only a point is labeled.

Thank you

Update: I tried a new way to add features

And the type of the feature is not reconized, surely undefined, i don't know why
