Output a file and re-input it within the same workflow

[joeltran]

Hi

I follow the instruction here to output a file then reinput within the same workflow. However, I keep getting this error message. "The field "FileName" is missing. Compare the tool configuration with the input stream". Could you please help with what went wrong please.

here is my initial input file

Dynamic Input

Many thanks,

What's your configuration here:

The workflow in the article works fine for me, does it work for you? Without seeing the error, it kind of just guessing on our end so any more information would be useful

Hi Calvin,

Here are some more screenshots. 

1. My workflow and error message.

2. Output File Set up with name "Output Y"

3. Dynamic Input set up

I still have an error though. 

Thanks,

@joeltran From your error, it looks like the FileName column (which you're using to update the dynamic input tool) is missing from your flow at the point of the dynamic input tool (the square number 3). Can you verify that that column does exist in your data? Check for trailing spaces as a common suspect
