Error Handling Mechanism
Hi, i have a question regarding the error handling mechanism
For the query function I provide the following arrow function:
() => axios.get('url').then(res => return res.data)
Why does react query know about the error that axios has if something went wrong? I’m returning the data and not the promise where ‘.catch()’ could be used by react query.
Could you help me to understand how this works?

resolved promise === data
rejected promise === error

Ok, but i do not provide a promsise. I only give the data with a resolved promise. Or is it implicite a promise because i do not return something outside ".then"?

the code you showed returns a Promise. that's how
.then works
