Error in the Lightning Connect module

When checking the challenge  I get a persisting issue with the "Phone Plan" external object 

Displayed message is : 
Challenge Not yet complete... here's what's wrong: 
There was an unexpected error in your org which is preventing this assessment check from completing: System.ExternalObjectException: data.api.DataSourceException: This data is no longer available. The "Phone_Plan" table in the external data source is currently unavailable. Try again later or contact your administrator for help.


I have tried with a new developer ORG and I get the same error.

Thanks.

Can you please provide a screenshot of your External Data source's configuration?

Hi Pcom,

This is the screenshot

So to start with, trailhead is not designed to work with a namedspace org.  So I would recommend that you try again with a new Developer Edition org [1] that does not have a namespace.  Secondly, it looks like the objects were renamed.  This could be a change in the data on the backend or it could have been something that you did.  When I validate and sync this odata endpoint, I get "phone_plans" and "phones" not their single noun versions.  I would delete the two external objects, re-validate and sync and then finish the work.  If that does not work then I would try again in a new Developer Edition org without a namespace.  Also, take a read over this [2] to ensure that you don't lose your existing trailhead badges by logging into trailhead with your primary account and then logging into the secondary org to do your trailhead work.

Try to sync again , And after sync try to edit the object name and label only. Not the table name

I ran into the same issue. I had to change the external data object names from phone_plans and phones to Phone_Plan and Phone. The excercise guide clearly says "Note that you will need to adjust the Object Names for the two external objects from the default setting after the initial sync". But once object names are changed they are no longer accessible/available. I've attemted several times but to no use. The solution seems to be 'Get a  new Dev Org' and that's not ideal.

Just had the same issue. After troubleshooting I found that I had not read the last line of the challenge carefully enough.

"Make sure that you don’t change the Table Name field in either external object."

When I double-checked my work I had copy-pastaed into the this field also, which fouled it up. When I fixed this field, all was good.

Try from different org. And start the challenge all over again. Use Trailhead Playground 2 instead of Playground 1. 

Dont change the table's name field, leave phone_plans and phones in external object.

Can any one please help me solving  this challege

Use Salesforce Connect to link an External Object with Salesforce Users
The mobile phones being tracked by an external application are used by specific users in your Salesforce instance. Create an indirect lookup relationship between the 'Phone' External Object and the 'User' standard object.
Create an OData 2.0 external data source with 'Mobile Devices' as the label, 'Mobile_Devices' as the name, and this URL: https://phone-odata-demo.herokuapp.com/devices.svc/. Note: If you have completed the previous challenge in this module ('Setting up Salesforce Connect'), the External Data Source should already exist in your Developer Edition.
Add a new 'Phone UUID' custom field on the User standard object with the resulting API name of 'Phone_UUID__c'. The field should be of type 'Text' and marked as 'Unique' and 'External ID'.
Change the 'UUID' field on the 'Phone__x' external object to be an indirect lookup relationship to the 'User' standard object. Use the 'Phone_UUID__c' field as the matching key for this indirect lookup relationship.
Update any existing User record in your Developer Edition instance to have a value of '0000123442' for the 'Phone_UUID__c' field.

I too am getting the same error despite a second playground, mutliple scenarnios tried, and making sure the table name is the same. In my very limited experience read of this, I think there is a fundemental issue with the heroku app link provided. That again is an uneducated conlusion here. I am having multiple issues with the heroku app url's (or apps) they are providing for these challenges.

And Salesforce support says that Salesforce Connect is out of their scope of support, so they can't help me. Is there anyone that can help me to solve it? please

I am receiving the same error too, I think theres an error in this Module, because there is the limitation on creating more than one External Data Source. I created one in a Trailhead Playground and the second one I created in a Developer Edition Org and I am receiving the same error:

One thing I noticed is: the challenge says to change the API name of the object to Phone_Plan__x and then it says to change to Phone__x, when I do that is shows an error saying that the object Phone_Plan__x does not exist. When we change the name again to Phone__x it shows the above error. I tried to recreate the objects by syncing again but the problem remains.

Hello,

Looks they completely removed the Salesforce Connect module from the Admin Advanced!!I am not able to see that module.

Thanks
