I had finally some time (or pushing reason because we want to move to production 😃 ) to investigate this.

vue-pdf (or pdf.js for that sense) uses a worker to fetch the pdf. for some weird reason very deep in the pdf.js it maintains some weird reference to the worker used for the previous fetch here:

https://github.com/mozilla/pdf.js/blob/56ae7a669099b3439b325e434fc6d981910db2c6/src/display/api.js#L1786-L1788

It can be fixed like this:

this.loadingTask = pdf.createLoadingTask(this.src)
await this.loadingTask.then((pdf) => {
    this.loadingTask._worker.destroy()
})

It is explicitly forcing the old worker to go away.

Thanks, this worked for me
