Stored Proc Reverse Engineering issue

I am getting the below error message when reverse engineering the stored procedure. I have several procedures with similar pattern, but only this one is throwing error, rest are successfully reverse engineered.

Unable to get result set shape for PROCEDURE 'dbo.sp_GetOrgLocationCategoriesWithStates'
The metadata could not be determined because the statement 'SELECT CAST(NULL as uniqueidentifier) OrgLocationCategoryID_PK, CAST(NULL as uniqueidentifier) OrgLo' in procedure 'sp_GetOrgLocationCategoriesWithStates' is not compatible with the statement 'SELECT OLC.[OrgLocationCategoryID_PK],OLC.[OrgLocationID_FK],OLC.[CategoryName],OLC.[CategoryCode],[' in procedure 'sp_GetOrgLocationCategoriesWithStates'.

Found it, i had to use nvarchar in the last result because my top query is returning data type of nvarchar.

Output from sp_describe_first_result_set was helpful in finding the discrepancy.

As I said, test with sp_describe_first_result_set
