Share found in unexpected polynomial

we have used tkey sdk for storing user keys and added 1 extra module to store recoverable 1 share on server instead of the question module.

But we get this error after some frequent logins and log outs:-

1304: “Share found in unexpected polynomial”,
can you suggest some issues due to which it can occur?

Hey Paras,

Can you give us some additional details on how you saved the share, which module did you use and how.
Code snippets alongside will be really helpful alongside the particular error message.

So basically we saved 3 shares 1 on device . 2nd on torus network. 3rd on our own server for that created a module named server storage. Got this error while calling the reconstruct key in core.ts in core module of @tkey. Attached screenshot for the line code where the error is mentioned.
