As I can see, `tdl` uses old JSON interface, Airgram has switched to the [new one](https://github.com/tdlib/td/blob/966621376b87fda5b9eb29dd2f4da7732bf1c654/td/telegram/td_json_client.h#L97-L158). I guess, it can be a reason of problem.

Can you try to edit [this row](https://github.com/airgram/airgram/blob/master/packages/airgram/src/components/TdJsonClient.ts#L208) in your `node_modules/airgram` package? ``` await this.handleUpdate(clientId, response) ``` to ``` this.handleUpdate(clientId, response).catch((e) => this.handleError(e)) ``` Does it help?

Hello, can you provide more information please? What kind of error? What do you see in the log with level 4?

Probably, [this answer](https://stackoverflow.com/a/36048721/9341665) is related to your case.

Hello, you should. Airgram uses [td_json_client](https://core.telegram.org/tdlib/docs/td__json__client_8h.html), so you need to build TDLib according the [instruction](https://github.com/tdlib/td#building). Path to the library you can pass by the [command](https://airgram.io/api-reference/configuration#nodejs-version) option.

No, you don't need to build TDLib if you want to install web version of the library: ``` npm install @airgram/web ```

I am not familiar with angular, but probably you need to copy worker files from `tdweb` package to the root directory of your project. See how it implemented in webpack...
