Bug: Command deno add logs error for JSR package without default export

[csvn]

When using deno add, I get errors if there is any JSR package that has no default export (.). For instance, installing @std/testing will make it so errors are printed every time I run deno add command. The command itself seems to succeed anyway, but the CLI command fails with a non-zero exit code, and a pretty verbose error message is printed. Is it mandatory to have a default export? If so, perhaps @std/testing should be updated, since it currently only has named subpath exports.

Reproduction steps

1. Create a new folder
2. Add JSR package via deno add with no . export (e.g. @std/testing@0.225.3)
   • deno add @std/testing@0.225.3
3. Install any other JSR package (e.g. @std/json)

Actual results

When installing @std/testing@0.225.3 the following errors is printed:

Created deno.json configuration file.
Add @std/testing - jsr:@std/testing@^0.225.3
error: Unknown export '.' for '@std/testing@0.225.3'.
  Package exports:
 * ./asserts
 * ./bdd
 * ./mock
 * ./snapshot
 * ./time
 * ./types

Installing another package via deno add (e.g. @std/json) will print the same error again.

Add @std/json - jsr:@std/json@^0.224.1
error: Unknown export '.' for '@std/testing@0.225.3'.
  Package exports:
 * ./asserts
 * ./bdd
 * ./mock
 * ./snapshot
 * ./time
 * ./types

Expected results

No errors

Environment

OS: Windows 11
deno 1.45.2 (release, x86_64-pc-windows-msvc)
v8 12.7.224.12
typescript 5.5.2

Hi @csvn
I attempted to reproduce the bug, but I wasn't able to encounter the error you described. Did I miss something?

Pretty weird, I'm on Linux and I'm having the same issue:
