I am developing an unofficial Telegram program using the Pyrogram library in a shell environment. After a user connects their account to my program, they can provide a list of phone numbers and messages to the program, and the program will send those messages to the numbers.
The workflow is as follows: each phone number is added to the Telegram contacts list using the import_contacts method, and then the send_message method is used to send the message to the numbers.
I have encountered a strange issue where some accounts encounter a "400 PEER_ID_INVALID" error in the import_contacts method, even though the phone number is correct.
To investigate further, I tested the phone number using the Plus application with the same account connected to Pyrogram. I tried to save the number in the contacts section to see if there is any issue. Surprisingly, I received a similar error through the Plus application as well.
However, when I tested the same phone number with a different account in the Plus application, the contact was successfully created.
Any insights or suggestions on why I might be encountering this error only with certain accounts would be greatly appreciated.
first_name = self.__get_first_name()
phone_number = str(self.phone_number).strip()
async with PyrogramClientCM.get_instance(self.bot_id) as app:
await app.import_contacts([
InputPhoneContact(phone_number, first_name)
])
