External function in Blazor

[dikan]

I have defined an external C# function in the Blazor application. I managed to add this functionality to a simple report and when I run the report in designer preview there is no error at all, just strings that are built with this external function are empty.
When I try to add this function to an existing report then I receive an error that says that this function is unknown and the report is not built. Same for calling this function from an application, a small example works with function and returns proper values but this complex report raises an error.

Where did I go wrong?

I discovered "Compilation mode".

Thank you.
