04/18/2026, 1:25 PM[telegram] Assertion Error: Unsupported message type from Telegram: {"update_id":433202787,
"message":{"message_id":89,"from":{"id":...}}}
Context:
* The error seems to occur when the user sends something that’s not plain text (e.g. contact share via request_contact, maybe other message types too).
* Standard text messages work fine.
* I suspect it’s related to how Botpress parses or normalizes certain Telegram payloads.
What I’ve tried:
* Logging the event object to inspect payload
* Handling event.payload.text vs event.payload.contact
* But the error seems to happen before my flow even processes it
Questions:
1. Does Botpress Telegram integration support contact messages (request_contact)?
2. Is there a list of supported Telegram message types?
3. Any workaround to safely handle unsupported payloads (event.payload.contact)?
Would really appreciate any insight or pointers
