Javascript async await returning single value of array [duplicate]

I'm trying to get data from an API call and update context with the result.

I have this function to get data, this should return an array:

export async function fetchAircraft(bearerToken) {
    const response = await axios.get(apiURL + 'User-getAircraft',
        {headers: {
            'Authorization': `Bearer ${bearerToken}`,
            'content-type': 'application/json'
        }}
    );
console.log('http resp: ',response.data);
return response.data;
}

I'm calling the fetchAircraft function from my dashboard:

useEffect(() => {
        async function getAircraft() {
            const aircraft = await fetchAircraft(userContext.idToken);
console.log('dashboard: ',aircraft);
userContext.setAircraft(aircraft);
}
getAircraft();
navigation.setOptions({
headerRight: () => (<AircraftSelector/>)
})
},[])

When my dashboard loads and I view the logs, the console log in the fetchAircraft function only shows a single item in the array (as does the console log in useEffect. If I comment out the userContext.setAircraft call, the console logs both show the correct array with all items included. I cannot figure out why the call to set aircraft in the context is limiting what is returned by the fetchAircraft function.
