I am trying to load the data to put into the database from a server however I have verified this is not the issue. the first one of these url ib request is getting a name of the document however this works well but the second one is where I get the field data the problem is loading it off a server

Answer 1

The data is being base64-encoded .

>>> s = 'aGVsbG8='
>>> base64.b64decode(s)
b'hello'

I don't use Firebase/Firestore but if the data is being automatically base64-encoded on write then most likely it will be automatically decoded when read.

If you need to manually decode it, note that base64.b64decode returns bytes , so you need to call .decode() on the bytes to get a str .

This comment on github suggests that adding the u prefix to string literals will make Firestore encode as UTF-8 instead of base64.

So in your example:

uname = u'Hello'
