Telegram-bot: Cannot read properties of undefined (reading 'length')

Hi everyone,

I am new to Buildship

I tried to call OpenAI AI Assistant in Telegram by following this youtube tutorial from buildship : https://www.youtube.com/watch?v=Pz1t1KCnrbs&t=578s

I have shipped this workflow successfully. However, when sending message in the Telegram bot, nothing happened, found the following error message in my workflows logs in buildship:

Telegram-bot : Cannot read properties of undefined (reading 'length')

Attached is the screenshot of my workflows and logs error messages

I tried to execute the openai node and it worked well, so I guess the issue is in the telegram bot.

Please advise, thanks a lot

Hi @samlira1705 The error

cannot read the properties of undefined reading length

cannot read the properties of undefined reading length

shows that the connection is not successfully set up for the Telegram bot, to debug this you can perform a quick test. In a new workflow, you can add the Telegram Bot Trigger and add a return node and in the value return the full object received by Trigger, and then try sending a message to the Bot and confirm if the object is reading the message text in it. You can confirm it by checking the logs - https://docs.buildship.com/logging.
