+### `ERR_UNSUPPORTED_RESOLVE_REQUEST`
+
+An attempt was made to resolve an invalid module referrer. This can happen when
+importing or calling `import.meta.resolve()` with either:
+
+* a bare specifier that is not a builtin module from a module whose URL scheme
+  is not `file`.
+* a [relative URL][] from a module whose URL scheme is not a [special scheme][].

+  await import('data:text/javascript,import "bare-specifier"');
+} catch (e) {
