cfssljson not parsing bundle output

Running the following

```

cfssl bundle -ca-bundle /path/ca.pem -int-bundle /path/intermediate_ca.pem -cert /path/web.pem | cfssljson -bare web-full
```
The call returns fine, but nothing is produced. Without piping to cfssljon I can see that the bundle does get produced.

```
sh-4.2$ cfssljson -version
Version: 1.6.3
Runtime: go1.18
