Filter an Embedded Dashboard - Module

I am not being able to verify my step in this module.

Getting the following error: The filter doesn't match the JSON string in the instructions. Check your filter carefully. Even one character missing or out of place can cause problems.

I have tried replacing the string as seen here , but its still not working. 

When creating a new Dev Org, I cannot see the Analytics Studio available in my new environment and trying to registering for a new one shows that my email (I tried more than one) is already registered.

Any help here?
