I pulled ghc gitlab repository by

```

git pull --recurse-submodules

```

But it failed with the following error.

```

error: Server does not allow request for unadvertised object 58a7ea0336363b29513164487190f6570b8ea834

Fetched in submodule path 'libraries/array', but it did not contain 58a7ea0336363b29513164487190f6570b8ea834. Direct fetching of that commit failed.

```

It seems the latest commit `58a7ea` of `array` library is not found on the server.

Are there any help on this?

Best,
