Trailhead challenge giving error

Hello Experts,

I have been doing Trailhead challenges. however i am getting below error for one of the trailhead challenge. could you help me on this ?

Trailhead Challenge : https://trailhead.salesforce.com/project/flow_satisfaction/flow_satisfaction_survey
Error : 
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. We recommend using a new Developer Edition (DE) to check this challenge. If you're using a new DE and seeing this error, please post to the developer forums and reference error id: WJCULLQI

Hi Ramu,

Sorry for this issue that you're encountering.

Can you please double check that your Developer Edition Org does not have any namespaces setup in it?Trailhead does not support namespaced DE Orgs and so if you have a namespace registered for the DE Org, you'll need to sign up for a new one and complete this module there.

When trying trailhead, we encourage users to create new Dev org's such that the previous config changes do not affect the trailhead challenge settings.

To login into trailhead you can use your old org but for activity(code and config) related changes you can use new org. In such a way all point will add in your old profile only.

Please check the below link for help. Note: Trailhead may get logged out of two reasons.
  1. You've been away for a while and you're now logged out of your DE. This can simply be resolved by logging in again and restoring the connection.
  2. No matter how many times you log out and log in again, having the security setting "Lock sessions to the IP address from which they originated" enabled will prevent you from connecting your Org to Trailhead. For some reason, when trailhead checks challenges, it doesn't use the same IP address throughout the transaction, causing the error because the connector was logged out.
Please mark this as solved if the information helps.


Regards,
Nagendra.
