Hi,
The trailhead project is title is something that I have completed and even data is correctly updated as provided in the module. Still the module doesnt show up as complete and results in error:

Step Not yet complete... here's what's wrong: 
The 'Tim Barr' contact record was not updated correctly in Salesforce. Please check your Heroku Connect setup. 
Note: you may run into errors if you've skipped previous steps.

I could clearly see that my change in updated heroku app traversed to SF Org and updated the required fields. But still I see below error.
