Describe the bug

Hey,
If url contains the text 'post' in the url its observed axios is adding extra '/' at the end while calling the api which results into 404 Not found.

e.g. formed url while calling - https://hostname/users/bhushan.joshi@gmail/EMP/temp-auth-method
final url - https://hostname/users/bhushan.joshi@gmail/EMP/temp-auth-method

But when its had 'post' in the url
e.g. formed url while calling - https://hostname/users/bhushan.postel@gmail/EMP/temp-auth-method OR https://hostname/users/bhushan.abcpostxx@gmail/EMP/temp-auth-method
final url - https://hostname/users/bhushan.postel@gmail/EMP/temp-auth-method**/** (adds extra slash in it)
