Fix SelectQueryError

in Supabase Auth

Solution

SelectQueryError in supabase-auth usually arises from type mismatches when the TypeScript compiler infers incorrect types after a database operation like `rpc()` or joins involving different schemas. To fix it, explicitly cast the returned data to the correct TypeScript type using `as` or define a more specific function return type using generics, ensuring the compiler understands the structure of the data you're selecting. This guarantees the expected schema and data types are aligned, resolving the mismatch.
