When creating a sharepoint site via a Nintex Workflow it’s best to remove any blank spaces from the url as these are converted to %20.
Most often these url’s are converted from a field a person has entered. You can explain the users that they shoudn’t use spaces or you can use Nintex to remove these blank spaces in the names.
You can easily remove the spaces by adding a Regular expression action with the following settings:
- Pattern: \s
- Replacement text: keep this empty
- Input text: the name
- Store result in: variable
