YDB GO SDK version:
v3.92.5
Environment
Linux, x86_64
Current behavior:
I came across a temporary error in a service using YDB SDK. But the reason (%!w(<nil>)) is not clear from the logs:

}
Expected behavior:
Wrapped error must be initialized.
Steps to reproduce:
No steps to reproduce.

It turns out that the lastErr is not initialized in some edge cases.
