I am using FileReadTool() in order to read a flat file, the issue it’s my file is separated by “|” because there are fields with “;” and “,” characters, also my data contains latin encode, when I run the crew I got this:

I encountered an error while trying to use the tool. This was the error: Arguments validation failed: 1 validation error for FileReadToolSchema

My question is:

Can I set something in the function: FileReadTool or have I to create a external function? how can I do?
