TypeError: expected string or bytes-like object about mail-parser HOT 11 CLOSED

Hi,
which version of mailparser are you using?

from mail-parser.

mail-parser==1.2.1
i can pm you the data. but i don't really want to post it publicly?

from mail-parser.

You could send me a mail on

mantuano.fedele at gmail.com

Is response_part[1] a byte type? Did you try with mailparser.parse_from_string?

from mail-parser.

i use pycharm and looked through it with the debugger.
code is below. the data inspected was of bytes type
this is in python3.6 and i forwarded you the unsanitised data to your email

def check_mail_by_id(self, message_id: AnyStr) -> mailparser.MailParser:
    _, header_data_raw = self.imap.fetch(message_id, '(BODY.PEEK[HEADER])')
    for response_part in header_data_raw:
        if isinstance(response_part, tuple):
            headers = mailparser.parse_from_bytes(response_part[1])
            return headers

from mail-parser.

In your header there isn't the to:

File "C:\project\venv\lib\site-packages\mailparser\mailparser.py", line 217, in make_mail
"to": self.to,
File "C:\project\venv\lib\site-packages\mailparser\mailparser.py", line 383, in to_
self.message.get('to', self.message.get('delivered-to')))

So the parsing fails because the email should have to.

Are you sure that you take all email with self.imap.fetch.
mailparser works with all raw mail.

from mail-parser.

well i'm parsing the headers first. You can see that i'm using the BODY,PEEK[HEADER] in the fetch
this mail when i checked in outlook didn't have anyone in the to section either.
the only thing missing should be the body of the mail.

from mail-parser.

The best way is:

• Get all mail, and put it in a variable
• Check with print the header (only for debug)
• I could fix this problem, but the mail should have a to in the headers

The code part is this.

from mail-parser.

i saw that. my issue is that this mail doesn't have a deliviered-to header. which makes the parser fail.
the mail is being read by imap from office365.
i don't want to pull the full mails as in my use case i'm accessing my own inbox and it's simpler to not have to mark everything unread again.

from mail-parser.

Ok, you can take only headers, and mailparser should work fine because there are mails without body or attachments.
In your mail there aren't to and deliviered-to header, because deliviered-to header is the fallback of to.
You can try to catch TypeError and print headers. Then post here obfuscated hearders, so I can check.

from mail-parser.

that's why i emailed you the headers.

Fixed with commit 0219562c84de32d63deb10417278380063337024
