How to convert a PDF from base64 string to a file?

Question

I have a PDF as a base64 string and I need to write it to file using Python. I tried this:

import base64

base64String = "data:application/pdf;base64,JVBERi0xLjQKJeHp69MKMSAwIG9iago8PC9Qcm9kdWNlciAoU2tpYS9..."

with open('temp.pdf', 'wb') as theFile:
  theFile.write(base64.b64decode(base64String))

But it didn't create a valid PDF file. What am I missing?

Extending @Jebby's answer using Base64 (had the same issue as @SmartManoj)

import base64
base64String = "JVBERi0xLjQKJeHp69MKMSAwIG9iago8PC9Qcm9kdWNlciAoU2tpYS9..."


with open("test.pdf", "wb") as f:
    f.write(base64.b64decode(base64string))
