Unauthorized downloading an individual file, but no problem downloading whole repository

[Corey Malcom]

I am successfully downloading the entire archived repository using the following url with 'Basic Auth' and an app password.

url:   https://bitbucket.org/<workspace>/<repoSlug>/get/<branchName>.zip

HOWEVER, if I do something similar to access an individual file with the identical 'Basic Auth' using app password, I get a 401 Unauthorized:

url:  https://bitbucket.org/<workspace>/<repoSlug>/raw/<branchName>/filename.json

If I put the second url into my browser it downloads the file just fine.

Can someone help with this inconsistency?  I need to be able to download the file at the root of the repository without having to extract the archive and get it that way.

Help appreciated!

These are the requests being made.  As mentioned the top request works fine to retrieve the archive, but the auth headers seem to be inconsistent with the individual file request:

const auth = new Buffer.from(`username:password`).toString('base64');
axios.request({ 
  method: 'get', 
  url: url, 
  responseType: 'stream', 
  headers: { 
    Authorization: auth 
  }
});

OR

axios.request({ 
  method: 'get', 
  url: url, 
  responseType: 'stream', 
  headers: { 
    auth: { username: 'username', password: 'password' } 
  }
})
