OpenCart: PAYMENTS_WRITE error on checkout

[wcalkins]

Getting this error when someone checks out with Square on my Opencart site.  It's a new site and Square Extension was just enabled.  Everything seems ok in the Square account- bank is verified.   I've tried reconnecting.  Here's the entry from the log file:

2019-01-23 19:26:32 - SQUAREUP RESULT: {"errors":[{"category":"AUTHENTICATION_ERROR","code":"INSUFFICIENT_SCOPES","detail":"The merchant has not given your application sufficient permissions to do that. The merchant must authorize your application for the following scopes: PAYMENTS_WRITE"}]}
2019-01-23 19:26:32 - The merchant has not given your application sufficient permissions to do that. The merchant must authorize your application for the following scopes: PAYMENTS_WRITE

Hi @wcalkins,

Welcome to the Seller Community!

Thanks for surfacing this. I don't have the answer for this on hand right now but I'll run this by our API folks for a closer look. 

Also, wanted to put in a quick plug for Square Connect's Stack Overflow page. It's been a great resource for our developer community, and there's already a ton of questions that have been answered there.

We'll be back as soon as we have more insight for you.
