Telegram Error on ERPNext - Cannot process any document

[moizsami]

Hi,

Suddenly whenever I try to save any document which should trigger the telegram notification on ERPNext. The document cannot save and I receive the following error.

Traceback (most recent call last):

I am using ERPNext 14, hosted on Frappe Cloud
Our whole system is dependent on your amazing notification system. Please help me with this. Thanks :)

Hi @yrestom , just wanted to ask were you able to check this issue and if there is any info about it please do share.

Thanks

@yrestom sorry to bother you. but can we expect a resolution in the coming days or is something that will take time, as the integration was being used by on many production sites and all are stopped.

I found the solution. The error was due to the python package not the integration app.
downgrade phyton library to v20

pip uninstall python-telegram-bot
./env/bin/pip install python-telegram-bot=20.0 --upgrade
bench build (important), bench migrate, bench clear-cache, bench restart
gave me the solution. Thanks for the awesome app.
