E001 - JSON5 syntax error

Cause

A deck or slide source file could not be parsed as JSON5. The parser rejected the input syntactically before any schema checks ran.

Example

{
  title: "My Deck"
  slides: []   // missing comma after the title value
}

How to fix

Read the parser message for the offending location. Common causes: missing commas between fields, unbalanced {}/[], unquoted string values. JSON5 allows trailing commas and unquoted keys, but not unquoted string values.
