When filtering the agenda view or run a filter the following error generates:
An unexpected error occurred. Please report this problem to your system administrator with the following information:
System.Data.EvaluateException: Expr_TypeMismatchInBinop
The functionality has been enhanced in Orchestrate version 7.66. Please upgrade to this version or above.
If the issue only occurs on one filter, check the condition being used. For example, if the filter was created selecting field Op Step with condition Starts With, this would generate the error because the Op step is a number field. So the filter cannot use 'Starts With' because that only works for text. Instead use the condition Greater Than (>) and Smaller than (<).
If the issue continues to occur, please raise a new case online and reference the title of this article.
