Axios instance not working after update to 0.21.4 from 0.21.1

[Alta1re]

Describe the bug

I updated from 0.21.1 to 0.21.4 in my react-native application, where i am using an axios-instance.
After the update, i got "Network Error".
When i omitted the instance, and used axios directly, it worked, but not with instance.
After downgrading back to 0.21.1 everything works fine again.

To Reproduce

Just used a simple instance, like shown in the docs.

Expected behavior

Axios should work with instance, or, if the usage of instance changed, we an update in the docs.

Environment

Axios Version 0.21.1 / 0.21.4
Additional Library Versions [e.g. React 16.13.1, React Native SDK42]

NodeJs 14 or 16 have this problem also .... half http/https queries doesnt work with this update sending "Bad json request" as reply

Which version of node are you using?

Which version of node are you using?

Right now 14.17.1 (tried also 14.17.6, and 16.8.0) and returned to 0.21.1 axios.
If I see it right the problem already discussed in closed topics but some cases still created "Bas json data"

    var rpcdata = JSON.stringify(requestData);
    if (rpcdata == '{}') {   // For method == Get sometimes api returns Error so fixing it
      rpcdata = '';
    }
    var headers = {'Content-Type': 'application/json', 'Accept': 'application/json'};
    if (customHeaders) {
      headers = customHeaders;
    }
    if (token && token.length > 0) {
      headers ['X-Auth-Token'] = token;
    }

    url = encodeURI(url);

    axios({
      url: url,
      method: method,
      data: rpcdata,
      httpAgent: httpagent,
      httpsAgent: httpsagent,
      timeout: timeout * 1000,
      headers: headers
    })
    .then( function (response) {

this code working with 0.21.1 but fails with 0.21.4

Latest version also breaks unit tests since the validators are now breaking (cannot read 'split' of undefined)

[Alta1re]

I am using node V14.16.0

[nerdbeere]

@Alta1re I tried reproducing this on runkit without success: https://runkit.com/nerdbeere/613710790e31ee0008798854
I also tried it on my machine with node 14.6 which also works.

Can you try building a minimal case where this bug is visible?

[luhc228]

Also not work with axios@0.21.4, but work with axios@0.21.1.

my Node.js version is v14.16.0

I fetch my api in my react component. I got the response successfully.

But the res object has not been consoled.

I fetch my api in my react component. I got the response successfully.

But you are not using an axios-instance.

With using axios directly i don´t have problems, too.
And i even get my response object.

When i create a bare react-app, and just insert an axios-instance and an axios call in App.js, i can´t reproduce this too.
But in my existing application (react-native) it´s definitely just changing the version of axios which changed the result of fetching.
At the moment i am quite busy with my application, i will do some more test, when i am finished.

[jasonsaayman]

Mm seems odd can you try give us a reproducible example @Alta1re

I am having the same issue. It is related to the package.json version on axios.

For some reason, this isn't getting the proper version.

I'm using node 12

[jasonsaayman]

Cool there is a fix #4029 as soon as it is rebased I will do a release

[varemenos]

Sorry to bother but was this ever released? I see that both this issue and #4029 are closed but no new version above 0.21.4.

[freddiegar]

You can use this version: v0.22.0 or +
