Issue description

I am trying library for the first time, and have updated my username/password and when I run the following code I get the follwoing error. This is with "pyticktick>=0.2.0"

I tried client.get_batch_v2 as well but it failed with error 429. I have attached my log below. In the log, my true username and password are not shown. Since the TickTick account I used is just for test purposes, I can provide the username and password to someone who wishes to reproduce the error.

Hi @ForceConstant,

In response to pydantic_core._pydantic_core.ValidationError: 32 validation errors for GetBatchV2:

Please add all validation errors you are getting, it appears to be getting cut off. In the short term you should be able to set override_forbid_extra to get around the error.

Hi @DougX71,

In response to ERROR | pyticktick.settings:_v2_signon:359 - Response [429]:

without understanding what understanding the code you are using. I am seeing a malformed dictionary here: {'v2_username': 'xxx': 'yyy'}. Could you please create a separate issue?

[DougX71]

I created a new issue, #226 for the 429 error during authorization
