Is this still working? i have tried it and i am getting this error "Uncaught TypeError: Cannot read property 'edges' of undefined
at XMLHttpRequest.onReadyStateChange (:27:81)". this would be reaaaaly helpful if it worked, Thanks!:)

I'm getting a similar error

For context, i'm leaving the browser on the instagram profile. I then paste the code and press 'Enter' and then I get this error.

Is this method still works in 2018

Hey @hardiksondagar, I tested the script, but when I pasted and executed it on chrome, console says "udefined", before calling the "downloadAsCsv() " function. How can I solve this? Thanks in advance.

have the same issue

@carlosMetrics @aliuzair @unnir, I've updated the script, it's working now.

Works with Chrome, but doesn't work with Firefox. It only manages to get the first 17 followers in Firefox. I'll be working on tweaking this to read my followings and then compare the two in excel hopefully. Thanks @hardiksondagar
