💻 Code

// The files: "code", "$code", and "$$code" all exist. "$$$$code" does not.
// However, the first line is the only one that has an error:
// "'"~server/$$code"' has no exported member named 'test2'. Did you mean 'test1'?"
import {test2 as test2_error} from "~server/$$code"
import {test2 as test2_working} from "~server/$$$$code"
import {test1} from "~server/$code"
import {test0} from "~server/code"

import {test2 as test2_2} from "./server/$$code"
import {test1 as test1_2} from "./server/$code"
import {test0 as test0_2} from "./server/code"

🙁 Actual behavior

It appears that $$ gets escaped / interpreted as reduced to a single $ but ONLY when using paths config.

🙂 Expected behavior

The filename imported matches the filename that you've written.
