What’s happening?
API calls are failing during resource assignment of project tasks, particularly when special characters such as '&' are involved. 

Reason:
The failure of API calls is often due to improper encoding of special characters in the query string. Specifically, the '&' character must be encoded to avoid conflicts in the query syntax. 

Resolution:
Ensure that special characters in the query string are properly encoded. For example, the '&' character should be encoded as '%26'.
Consider using the encodeURIComponent function to dynamically encode special characters in the query string.
