This one in particular may happen when iterating over messages,
perhaps more likely to happen if the group was created in a
different data center.
A small sleep of a few seconds also greatly increases the
chances of the error going away.
It was actually using FileLocation, which had the invalid expected
type for what was being returned. Instead it should have been this
other type.
In addition, more parameters are passed so that the method can have
all the information it needs to correctly cast the type.
Excepting ValueError when creating the SQLiteSession could hide
other errors (e.g. using a newer session file on an older version
of the library). Instead, the original error is raised, as if
sqlite3 was being imported within its __init__ method.
Letting _get_extension work for photos even when the only information
available is a stream or a few bytes allows sending arbitrary bytes
as photos, if force_document was not set to True explicitly.
* Create `_NOT_A_REQUEST` when needed. Currently, modifications
in the raised exception would be "global".
* `retries` parameters were actually attempts. This has been fixed
to actually be the amount of retries, so 0 now means don't retry.
* Helper function to deal with retries instead of using a range with
different styles every time.
Things like SQLAlchemy work correctly only for timezone-aware datetimes.
The returned TLObjects all have them, but those that are manually created
were missing them, so serializing the state into SQLAlchemy sessions failed.
These two occur when replying to an inline query with a photo and
InputBotInlineMessageMediaAuto empty message, and passing URLs to
PNGs that may not be accessible (i.e. 403 from pixiv).
The salt1 that is sent to the server requires an additional 32 bytes
of random data. It's easy to miss this requirement from reading the
tdesktop source, because this extension is done in a function called
`ValidateNewCloudPasswordAlgo`.
