Telegram's documentation page on Error handling does not contain an
exhaustive list of all errors (in fact, it seems nobody knows!). This
repository contains a file called errors.csv with the known errors,
code and description.
If an error has a capture, it will be within curly braces, for example
in {seconds} for FLOOD_WAIT_X, indicating what the _X represents.
You can contribute by expanding the list, improving the description, or testing for the validity of the errors.
The file methods.csv contains data about which methods can throw
which errors.
Please keep the lists sorted when contributing.
