TypeError: Cannot cast NoneType to any kind of Peer..

[0x4442]

Hey,
I've some trouble using the checker. Some of my phonenumbers working fine. But some throw the following error:
error": "TypeError: Cannot cast NoneType to any kind of Peer.. --> The error might have occurred due to the inability to delete the phone_number='[phone]' from the contact list."

I can't find the problem, why this happens random to some phonenumbers. If a number works, it works every time I try, same with numbers which didn't works.

Thanks for help.

I've been having the same issue recently, I think it might be related to whether accounts have usernames set.

@0x4442, your issue should be solved now, you'll need to reinstall the tool with:

pip install telegram-phone-number-checker==1.0.6

Please let us know if you have any further issues!

Hey @GalenReich ,
thanks for your fast response. It now works and don't throws the error anymore. But there is now a new "feature" ;)

before the patch when I search for a phonenumber he gives me all information back: phonenumber -> ID, name, username... or the error. Now I do the single search or multi search and get only: phonenumber -> ID and no error.
Output before the patch:
{ }, "[phone]": { "id": 321654987, "username": "Galen_Reich", "first_name": "Galen", "last_name": "Reich" } }

Output after the patch:
{ "[phone]: { "id": 789456123, "username": null, "first_name": "", "last_name": null }, "[phone]": { "id": 321654987, "username": "Galen_Reich", "first_name": "", "last_name": null } }

Hmmm, I can replicate this, but I don't think it originates with my changes (as much as I like introducing new features 😅). It could be that Telegram is returning different information.

Would you be able to pip install telegram-phone-number-checker==1.0.5 and check that the output before the patch still returns the first_name and last_name fields?

[0x4442]

I did, installed with 1.0.6 and it works with complication (error is gone but last_name/first_name is empty/null) as written before. Tried in another VM with 1.0.5 and it come to the error as i opened this issue but showed first_name and last_name correct.

[Galen Reich]

When I run 1.0.5 I don't get first_name last_name anymore (I did a few days ago). I suspect Telegram has changed something in the last few days.

But if 1.0.5 is still returning first_name last_name for you, then I'll need to look closer!

From my testing it looks like Telegram is not resolving a number into a name unless that number has added you as a contact.

[0x4442]

well i can confirm that in 1.0.5 i get with the "problem"-number the error and with the other all data ID, first_name, last_name, username. In 1.0.6 the "problem"-number give ID and no error, but the other number gives back the ID too. I think it has something to do when a number have no username/last-/first-name.

[Galen Reich]

Okay, that's really useful to know, thank you! I think you are right, perhaps chaning to not match by username has had this unforeseen consequence - I'll reopen this

[Galen Reich]

Okay, second time lucky - hopefully 1.0.7 fixes all the issues!

tried and works completely fine! Thanks for your help and fast response.
