Diagnostic error in lazy syntax

[niksingh710]

why this error is there and is there any solution?

I don't use/know lazy.nvim, but reading the message Cannot assign "string" to "(string|LazyPlugin)[]" makes me think that you're trying to pass a string where an array of strings is expected. Try plugins = {"firenvim"} instead.

Don't know how but the diagnostic is gone for now.
i changed nothing.
keeping it here for future reference if faced again.
