The confusingly named
messageTextproperty ofDiagnostichas the typestring | DiagnosticMessageChain. That is, it could be a message, or a chain of error messages (which happens if you have an error nested in a type somewhere.Previously, if an error had a message chain, the output was something like
L123 [Object object]. This changes it to use the methodts.flattenDiagnosticMessageTextwhich does exactly what you'd hope.Small additional change: I don't know if it was just my own settings, but TypeScript was complaining about the line
