**Description**  
Afer I call login, I fetch last error through GetZoomLastError() and get these error.

ErrorType=LastErrorType\_Auth  
ErrorCode=22015  
ErrorDescription=SDK internal error. You can retry this feature by restarting the program. If you still cannot solve the problem, please contact our support engineer.

and other last error, example:  
type=meeting,  
code=22004,  
description=The SDK can not find the corresponding zoom dll file, or the corresponding zoom dll file is incorrect, please check if the sdk package is correct.]||

type=meeting  
code=22002  
description= Make sure the SDK service is already created and enabled before call this method.]|

But the sdk seams works well, even it has these error.

**Which version?**  
[v4.6.15074.0203](https://github.com/zoom/zoom-sdk-windows/releases/tag/v4.6.15074.0203)

Hi [guan\_bj](https://devforum.zoom.us/u/guan_bj),

Thanks for the post. The interface GetZoomLastError() is expected to be used when the meeting status is not successful (when an error happens). If there is no error that will affect the usage, please don’t worry about the message from this interface as they are some warnings.

Thanks!
