This is my code

Please upload pdf here

<form id="upload-form" method="post" enctype="multipart/form-data">
  <!-- <label for="file">Choose file:</label> -->
  <input type="file" id="file" name="file" accept=".pdf" />
  <input type="submit" value="Upload" id="upload-button" disabled />
</form>

<div id="errordisplay"></div>

after uploading pdf i summarize the data in that file. it works in another frappe-bench. Here it always gives the above error. same code only. How to solve. I tried bench update --reset also

this is my python code

@frappe.whitelist(allow_guest=True)
def pdfconvertor():
if ‘file’ in frappe.request.files:
file = frappe.request.files[‘file’]
# Read the PDF and extract data
text = read_pdf(file)
# return text
# Clean the extracted text
# cleaned_text = clean_data(text)
# Summarize the cleaned text
summarized_text = summarize_text_with_sumy(text, 20) # Adjust the second parameter to change the number of sentences in the summary
return summarized_text
else:
frappe.throw(_(“No file found”))

@frappe.whitelist(allow_guest=True)
def read_pdf(file):
resource_manager = PDFResourceManager()
fake_file_handle = io.StringIO()
converter = TextConverter(resource_manager, fake_file_handle, laparams=LAParams())
page_interpreter = PDFPageInterpreter(resource_manager, converter)

for page in PDFPage.get_pages(BytesIO(file.read()), set()):
    page_interpreter.process_page(page)

text = fake_file_handle.getvalue()
converter.close()
fake_file_handle.close()

if text:
    return text

please help on that. thankyou

Where are you calling your upload API? Because it is not in the form action, so you might be manually calling it with the file, can you share that part?
