Hi @Valdinei_Duarte

Welcome to the n8n community!

I have tried to reproduce the error that you’re facing on my end by testing out the “Extract from File“ node by receiving data from a test HTTP Request:

https://people.sc.fsu.edu/\~jburkardt/data/csv/hw_200.csv

The Extract from File node is failing because the data from your previous node isn’t passing the uploaded file as binary data. To fix it, it’s important to receive the data as a binary file. I see that you are using HTTP Request nodes. The error on your end means that the node couldn’t find the binary file field named “Arquivos”. You need to select the Response Format as “File” and then the exact same name for “Put Output in Field” will go as “Input Binary Field” for the Extract from file node. In my case it is “data”:

After that, the HTTP request sent the file as binary input (under the data field), and the Extract from File node is able to process the file details:

You could follow the same approach for triggering your workflow and fixing the 400 Workflow error.

Hope this answers your question.
