You can’t send a file using that activity.
Activities - Generate Text Completion
Generate text completion will just take a string input (your prompt) and then generate something as an output.
What you’re doing now is just sending the file name in the prompt.

To use that activity you would have to extract the text from the document and then feed it into the prompt.
See this use case from Anthropic:
