I'm stuck on step #2 of Einstein Analytics and Discovery Insights Specialist superbadge.  I'm getting this warning while checking the challenge:

The step "Churn Tenure' is in compact form, so the filter values need to be specifed as a minimum and maximum
The static step that feeds has the following the value:
 

"Tenure_Length": {
                "broadcastFacet": false,
                "label": "Tenure Length",
                "selectMode": "single",
                "type": "staticflex",
                "values": [
                    {
                        "display": "High Risk",
                        "value": "1 to 12 months",
                        "min": 1,
                        "max": 12
                    },
                    ...
                ]
            }

I'm using selection binding for min and max values.  The dashboard is correctly filtering:


Any ideas? 
I've tried a non-compact form step where I inject a saql fragment into the query, as well as where I inject min/max values using a range filter serialization...All these efforts end in the same challenge failure message.

Any help/suggesitions are welcome!

I am on Step 7 of the superbadge and getting this error and I didn't change anything except what the challenge was asking in the playground. any thoughts?
Challenge Not yet complete... here's what's wrong: 
There was an unexpected error while verifying this challenge. Usually this is due to some pre-existing configuration or code in the challenge Org.

Challenge #3
After a number of mis-starts, I have passed this challenge. However, I am not convinced that my code is doing what it should (or anything!).

If I don't specifiy the full https path in my callout (and just use the named credential as I beleive I should) I get an unathorized error:
14:28:29:005 CALLOUT_REQUEST [24]|System.HttpRequest[Endpoint=callout:ProjectService, Method=POST]
14:28:29:348 CALLOUT_RESPONSE [24]|System.HttpResponse[Status=Unauthorized, StatusCode=401]

The details in the named credential appear fine (I can use them and login manually).

If I include the URL in the callout (!!!?), I appear to authorize ok - however the response 'Not Found' is the same result I get if I connect to the site and logon manually:
13:36:08:006 CALLOUT_REQUEST [24]|System.HttpRequest[Endpoint=callout:ProjectService/https://sb-integration-pms.herokuapp.com/projects, Method=POST]
13:36:08:393 CALLOUT_RESPONSE [24]|System.HttpResponse[Status=Not Found, StatusCode=404]

I'm sure I'm doing something silly here but can't spot it. 

BTW
I also passed the challenge with no code to change the opportunity stage to submitted project/resubmit project. This doesn't matter but building this code does make repeated tests faster.

Error retrieving JWT bearer token for partner community users. Works fine for internal salesforce classic users. Connected app setup has "Admin approved users are pre-authorized" and so does "Perform requests on your behalf at any time (refresh_token)" checked along with other permissions on the app. The connected app also has the same permission set assigned that the partner user and the community has. Able to login directly to community with Partner community license user but fails to Get the JWT. Any known issue with partner portal and JWT? Or am I missing some config? Thanks in advance.

Very frustrating. I've attempted this challenge in the DE I was previously working in where I created the reports that need to be added into the dashboard. I have now tried it in two separate NEW DEs where I recreated the reports and built the dashboard. The error code has changed from yesterday but the end result is the same:

Any suggestions on how to move forward. The Dev Community account is new. However, this would be my 129th Trailhead badge.

Hi all, I am stuck on the prevent SOQL injection trailhead, where I am looking to determine which portions of the code I would need to invoke escapeSingleQuotes or whitelist to enable. I've made several attempts at investigation to little avail. I have appended my code are there any steps I would need to take. My goal is to assess the code to see how it works and what I would need to do.

Hope it helps.
