Error "Valid api_id must be provided" only on x64

[Maddest]

Hi,
I'm using the tdjson.dll v1.8.8 compiled for Windows C++ win64. All library functions work fine. However, after I have received the 'authorizationStateWaitTdlibParameters' I use 'td_send' to send the following JSON auth string:

{
"@type":"setTdlibParameters",
"parameters":
{
"use_test_dc":false,
"database_directory":"",
"files_directory":"",
"database_encryption_key":[],
"use_file_database":false,
"use_chat_info_database":false,
"use_message_database":false,
"use_secret_chats":false,
"api_id":12345,
"api_hash":"xxxxxxxxxxxxxxxxxxxx",
"system_language_code":"en",
"device_model":"Desktop",
"system_version":"",
"application_version":1,
"enable_storage_optimizer":1,
"ignore_file_names":false
}
}

I have followed the hints from #2155 and changed the JSON string accordingly, but then I get a JSON parse error (expecting string, not array).

Any hints what I'm doing wrong here? Thanks a lot!

"database_encryption_key" should be a base64-encoded binary string and not an array.

[Maddest]

Thanks. I don't have any database encryption keys, so I leave them empty. The last JSON string I used as follows, but I still get the API_ID invalid error.

{
"@type":"setTdlibParameters",
"parameters":
{
"use_test_dc":false,
"database_directory":"",
"files_directory":"",
"database_encryption_key":"",
"use_file_database":false,
"use_chat_info_database":false,
"use_message_database":false,
"use_secret_chats":false,
"api_id":1245678,
"api_hash":"xxxxxxxxxxxxxxxxxxxxxxxxxxxxxx",
"system_language_code":"en",
"device_model":"Desktop",
"system_version":"",
"application_version":"0.1",
"enable_storage_optimizer":false,
"ignore_file_names":false
}
}

Did I miss something different? I tried so many combinations, but it won't work.

I have downgraded to v1.8.1 and now it's working with the following JSON:

{"@type":"setTdlibParameters","parameters":{"use_test_dc":true,"database_directory":"C:\xxxxxxxxxxxxxxxxxxxx","files_directory":"","use_file_database":true,"use_chat_info_database":true,"use_message_database":true,"use_secret_chats":true,"api_id":12345678,"api_hash":"xxxxxxxxxxxxxxxxxxxxxx","system_language_code":"en","device_model":"Desktop","system_version":"0.1","application_version":"0.1","enable_storage_optimizer":true,"ignore_file_names":true}}

Since which version is use_test_dc available?

@Maddest Starting from TDLib v1.8.6+ setTdlibParameters values must be inlined and i can see in your JSON examples you haven't inlined the parameters.

To inline setTdlibParameters values remove the key/array parameters. So your JSON will be like:

{
"@type":"setTdlibParameters",
"use_test_dc":false,
"database_directory":"",
"files_directory":"",
"database_encryption_key":"",
"use_file_database":false,
"use_chat_info_database":false,
"use_message_database":false,
"use_secret_chats":false,
"api_id":1245678,
"api_hash":"xxxxxxxxxxxxxxxxxxxxxxxxxxxxxx",
"system_language_code":"en",
"device_model":"Desktop",
"system_version":"",
"application_version":"0.1",
"enable_storage_optimizer":false,
"ignore_file_names":false
}

This should work fine in TDLib 1.8.6+. Also i suggest you to read this #2155 (comment)

[Maddest]

@AYMENJD That works great...thank you very much for this information. It saved me hours 🥇

Are these changes documented somewhere? Can't find any changelogs.

[AYMENJD]

Yes but not in changelogs. Everytime you update TDLib you must check changes made to td_api.tl which is TDLib API scheme file. Which will help you to know more about the latest API changes.

[Maddest]

@AYMENJD Thanks. I'll check this file from time to time. However, a page with all changes listed for each version would be very handy though.
