Ah, if you did `./launcher enter app`, it’ll make you `root`. It seems like you’ll need to switch to the `discourse` user to get Database access. This should do it:

```plaintext
sudo -EH -u discourse bin/rake "revisions:debug_deserialization"

```

The kind of output we’re looking for is

```plaintext
Checking 5 PostRevision records in batches of 1000... this may take some time...

Done

---- Summary ----
Checked records: 5

---- Examples ----

```

(although obviously, if there are issues then the “Examples” section will not be empty)
