Answer 1

Just a suggestion, Check if the function createWorker() is not properly imported or if there is an issue with the library you are using and also check that you have installed the necessary dependencies

Answer 2

Use this version = "tesseract.js": "^2.1.5" it will run.

Answer 3

Update the syntax to the version of Tesseract you are using. Try replacing

const worker = createWorker();
await worker.load();
await worker.loadLanguage("eng");
wait worker.initialize("eng");

with

const worker = await createWorker("eng")
