Hello,  
[Document2.pdf](https://pdfjs.community/uploads/short-url/g94H9cPCob7B85ZRLnMFnxlVKbs.pdf) (76.7 KB)

Promise is never resolved if pdf contains a blank page.

On version 8.7.4 the problem is here. It worked well on 8.7.0

```javascript
Core.documentViewer.addEventListener('documentLoaded', async () => {
    await initAnnotate();
});

const initAnnotate = () => {
    console.log('initAnnotate');

    return new Promise(resolve => {
        const searchMode = Core.Search.Mode.REGEX | Core.Search.Mode.HIGHLIGHT | Core.Search.Mode.PAGE_STOP;

        const searchOptions = {
            fullSearch: true, // search the full document,
            onResult: (result) => {
                console.log('onResult');
            },
            onDocumentEnd: () => {
                console.log('onDocumentEnd');
                resolve();
            }
        }

        let searchText = "test";

        Core.documentViewer.textSearchInit(searchText, searchMode, searchOptions);
    });
}

```

Hello axeld,

Can you try handling the onError, onResult, and onPageEnd callbacks? There could be an error that is occurring.

Best regards,  
Tyler

Hello tgordon,

I already tried to log those callbacks, no errors reported. Plus, 8.7.0 works well.

Hi axeld,

Loading the code you provided I see the promise resolve, I modified the resolve to include some text to log. It logs in the console correctly.

```javascript
      const { documentViewer, Annotations } = instance.Core;
      const annotationManager = documentViewer.getAnnotationManager();
      documentViewer.addEventListener('documentLoaded', async () => {
        initAnnotate().then((value)=>{
          console.log(value)
        })
    });
    
    const initAnnotate = () => {
        console.log('initAnnotate');
    
        return new Promise(resolve => {
            const searchMode = instance.Core.Search.Mode.REGEX | instance.Core.Search.Mode.HIGHLIGHT | instance.Core.Search.Mode.PAGE_STOP;
    
            const searchOptions = {
                fullSearch: true, // search the full document,
                onResult: (result) => {
                    console.log('onResult');
                },
                onDocumentEnd: () => {
                    console.log('onDocumentEnd');
                    resolve('documentEnd');
                }
            }
    
            let searchText = "test";
    
            documentViewer.textSearchInit(searchText, searchMode, searchOptions);
        });
    }

```

Best regards,  
Tyler

Ok my bad, I uploaded the wrong document. Can you try with this one ?  
[lastpage.pdf](https://pdfjs.community/uploads/short-url/5wvqzduIWVmpeOGeaZBcsDN0XDK.pdf) (29.0 KB)

I copy/paste your code, and the promise is never resolved. I also tried onError callback, and nothing is logged.

8.7.0 still working with this document, but not 8.7.4.

Thanks.
