Python gets KeyError in put images FPDF

Question

Anyone who can help me about FPDF error because I was trying to regenerate PDF, but got the following FPDF error:

 File "/usr/local/lib/python3.5/dist-packages/fpdf/fpdf.py", line 1230, in output
   self.close()
 File "/usr/local/lib/python3.5/dist-packages/fpdf/fpdf.py", line 322, in close
   self._enddoc()   # close document
 File "/usr/local/lib/python3.5/dist-packages/fpdf/fpdf.py", line 1868, in _enddoc
   self._putresources()
 File "/usr/local/lib/python3.5/dist-packages/fpdf/fpdf.py", line 1791, in _putresources
   self._putimages()
 File "/usr/local/lib/python3.5/dist-packages/fpdf/fpdf.py", line 1706, in _putimages
   del info['data']
KeyError: 'data'

The template has images but I'm not sure about the issue. Please refer below.

    def start(self, data, display=''):
        """ Start PDF """

        content = data['data']
        file_name = data['file_name']

        self.front_page(data)
        self.render_data(content)
        self.output(file_name, "F")

The issue is in this part of the pdf library:

 def _putimages(self):
        filter=''
        if self.compress:
            filter='/Filter /FlateDecode '
        i = [(x[1]["i"],x[1]) for x in self.images.items()]
        i.sort()
        for idx,info in i:
            self._putimage(info)
            del info['data']
            if 'smask' in info:
                del info['smask']

Answer 1

I was facing the same issue,What helped me is to initialise pdf=FPDF() every time either inside a function or while calling recursively

Answer 2

I used FPDF2 for image processing and solved it with the way of initialization. Thanks
