TelegramBotHandler: API returns error when truncating/splitting in HTML parse mode
Monolog 3.9
I set $parseMode to 'HTML' and keep the default $splitLongMessages as false.
When the message is looooong, it gets truncated. If the truncation happens inside HTML tag, the Telegram API returns error 400:
Bad Request: can't parse entities: Can't find end tag corresponding to start tag "code"
In my example the loooong string has <code>blah blah</code>. Lets say it gets truncated at first blah, then the </code> is gone and API complains.
- Possible solution 1: would need to fix (actually parse?) HTML if truncating?
- Possible solution 2: strip HTML tags when truncating? (kinda ugly)
- Low hanging fruit: at least want about that in the (php) docs?
EDIT: actually, with $splitLongMessages=true same kind of problem – the message splits inside HTML causing Telegram API error(s).
@MacDada I can work on this issue. Can I get it assigned as part of Hacktober fest 2025?
Yeah, well… why not… we can compare results as I've actually got splitting (almost) done :D
