I added a filter to an export request, but the following error is generated in execution:

"ParseException: No property or field 'i' exists in type 'Customer'"

What it's mean ?

Can you provide more info about the application and data source type? Is it server-side Blazor or WebAssembly? Is it OData data source or some SQL database?

Put `server\Controllers\ExportController.cs` in the application ignore list:

and remove `.Replace("i =>", "")` from the `ApplyQuery<T>()` method:

Fix will be released before the end of the week.
