Cannot use widget app

[xiapoy]

Hi, I get this error while trying to use my widget app:

account = mkm.account_management.account()

ValueError: Only unicode objects are escapable. Got oauth_token of type <type 'str'>.

My .bash_profile looks like this:

export MKM_APP_TOKEN=4kQ(...)
export MKM_APP_SECRET=fSx(...)
export MKM_ACCESS_TOKEN=
export MKM_ACCESS_TOKEN_SECRET=

Also thanks for this great package 🙂

Hi @naileakim, thank you for reporting the issue. I'm looking into it.

Hi @Alien1993,

Thanks for your reply, here are some updates that may help you solving the issue:

I am using mkmsdk 0.4.0 and python 2.7.12. You can find the complete log below:

ValueError: Only unicode objects are escapable. Got oauth_token of type <type 'str'>.

And finally, a quote from OAuthLib FAQ:

What does ValueError Only unicode objects are escapable. Got one of type X. mean?

OAuthLib uses unicode everywhere and when creating a OAuth 1 signature a number of parameters need to be percent encoded (aka escaped). At least one parameter could not be encoded. Usually because None or a non UTF-8 encoded string was supplied.

Let me know if you need any other information

@naileakim I've fixed the issue and released a new version. Update to 0.4.1 and you're ready to go.

Thank you again for reporting the issue. :smile:

[xiapoy]

Thanks that's awesome, I upgraded to version 0.4.1.

Unfortunately I still get an error, this time about connection:

ConnectionError: Request failed
Status code: 401
Response message: Unauthorized

That looks like issue #2

[silvanocerza]

What call are you making when getting that error?

[xiapoy]

I was calling mkm.account_management. I just figured out that other calls likemkm.market_place are working now 😊

I guess it's because a widget app has only access to non-personal information.

Thanks for your great help!

[silvanocerza]

Good to know everything it's working correctly. 👍
