Checks

• I have checked that this issue has not already been reported.
• I have confirmed this bug exists on the latest version of pyticktick.

Reproducible example

import json
from pyticktick import Client

client = Client(v2_username="username", v2_password="password")
resp = client.get_batch_v2()

print("My Projects:")
for project in resp.project_profiles:
    print(json.dumps(project.model_dump(mode="json"), indent=4))

print("My Tasks:")
for task in resp.sync_task_bean.update:
    print(json.dumps(task.model_dump(mode="json"), indent=4))

Issue description

The client authorization is now working with the upgrade to 0.3.0, but the line resp = client.get_batch_v2() is generating Pydantic errors.

[DougX71]

I notice that this issue is similar to #149 in that it is for Pydantic errors when invoking get_batch_v2 but I don't have the "Extra inputs are not permitted" errors but instead have an "Input should be a valid string" error for InboxId and an "Input should be a valid list" error for projectProfiles. So, I created a new issue.

For both InboxId and projectProfiles Pydantic is saying the input value is None.
