This TypeScript error occurs when there are two fields with the same type of keys and values in one interface:

interface Test {
  [key1: string]: string;
  [key2: string]: string;
}

It may be because of the "interface merging" feature in TypeScript:

// file 1
interface Test {
  [key1: string]: string;
}

// file 2
interface Test {
  [key2: string]: string;
}

Can you do ctrl/cmd + click on the interface name (Test in my example) and see if there are multiple definitions that form this scenario (the key names are different, but the types of keys and values are the same)?

If they come from two packages, the simplest way is to use pnpm.overrides to restrict the versions.
