Execute failed: Cell count in row "Row0_?_?" is not equal to length of column names array: 1 vs. 0

Does anyone know how to solve this error?

I am working on a duplicate row filter node. The setting of this node is as follows.

It keeps duplicate rows, and it supposed to be no duplicate rows, but I don’t know why there is this error.

Hello @ThomasChen,

Could you send your workflow that you are having the issue with if possible?

I think the issue may lie with the type of input data being passed to it.
