Text replace

[rozxter1]

Is there any working example for text replacing with current Hummus version used ?

I have tried for text replace #71 (comment) - is not working with current HummusJs version (1.0.110) .
Gives error :
TypeError: pageObject.getDictionary(...).toJSObject(...).Contents.getObjectID is not a function
Disabling that line, gives new error:

const readStream = copyingContext.getSourceDocumentParser().startReadingFromStream(textStream)
                                                                            ^
TypeError: Wrong arguments. provide a PDF stream input

All other examples around web whats based on that reply also is not working.
Maybe someone can say what version was used for that example?

Thank you!
