Axios will, by default, attempt to POST your data fields as JSON which is not correct.

Instead, you want to url encode them and post the url-encoded string in the HTTP body. See the 'example call' in the docs.

There's a good example of how to url encode w/ axios here.

I also note that your redirect_uri field is already url encoded, so attempting to simply encode it a second time means you'll end up with something like http%253A%252F%252Flocalhost which is not correct. Double check your URL encoding against the example call to make sure you're not accidentally encoding certain fields twice. From memory the access code is already encoded appropriately so you might need to fiddle with decoding it before re-encoding it to get it working.
