Possible Reasons:

1. Missing | before derived table sql statement for old LookML
2. There is a non-supported character, like a degree symbol °, ç, ã
3. include contains an array of object like: include: ["viewname1.view.lkml", "viewname2.view.lkml"]
4. A dimension includes an action" parameter
5. A dimension/measure named 'yes' or 'no' or a reserved keyword
6. A circular reference in the LookML
7. A never ended sql parameter in the LookML
8. In a localization file (.strings), there is a wrong # to make a comment instead of a //
9. In the aggregate table, the timezone is wrapped with [ ]
10. A field that uses the {% parameter parameter_name %} Liquid variable is being listed in the fields explore parameter.
11. You have a VPN enabled.
12. You are using create_process inside of derived tables, without persisting them.

It's none of these!
