It looks like the problem still occurs for me, even with your change

[kminhc]

This seems strange. On my end this exact change makes it work, because the requestOptions then looks like this

{
  "method": "GET",
  "url": "https://example.com/articles",
  "params": {
    "_limit": 1000
  },
  "headers": {
    "Authorization": "Bearer TOKEN"
  }
}

which should be correct according to axios documentation

instead of

{
  "method": "GET",
  "url": "https://example.com/articles",
  "params": {
    "_limit": 1000
  },
  "headers": {
    "header": {
      "Authorization": "Bearer TOKEN"
    }
  }
}

This fix works well for me.

Thanks for your responses. I double checked and the problem was coming from my environment, so my bad!

The change looks good and fixes the problem. I'm not sure what caused the problem in this specific release though. But it seems ready to merge @alexandrebodin 🙂
