### Common Errors

Common index errors are represented in the below table, including descriptions.

| **Error** | **Description** |
| --- | --- |
| **Convert* Empty** | Conversion of native was successful, but there was no output text. |
| **Convert* Failures** | Error when extracting text and creating html from the native. These are typically corrupt or encrypted files. |
| **Empty Source** | The file is empty, so it has no content to extract or convert. |
| **File contains no usable text** | Includes non-text searchable files, i.e. non text searchable PDFs or image based files. For PDF-based files, re-OCRing from the Review Grid may extract additional text. |
| **File Conversion is not supported** | The source file was not found during indexing. |
| **File type is not supported** | A typical error when running Spreadsheet View index on non-excel file types. Best practice is to isolate spreadsheet files and run the Spreadsheet View index. See [Generate Native PDF and Spreadsheet Views](/reveal/docs/generate-native-pdf-and-spreadsheet-views) for more information. |
| **Insert Failures** | There was a failure when attempting to add the document’s text to the Elastic Index. |
| **Missing** | The native was not found. |
| **Not Defined** | The path to the OCR or native is missing. For third party loads, check load file paths. |
| **Not Supported** | Error when extracting text and creating html from an unsupported file type. |
| **Too large** | The file is larger than the size limits set within the Text Set settings. It’s recommended to download and view these files natively. |
| **Unknown Exception: 4** | Rarely seen, usually linked to the Extracted text set index where the document contains no indexable text. |

* “Convert” is the process of extracting text and rendering html from the native.

### Common Alerts

Common alerts are represented in the below table, including descriptions.

| **Alert** | **Description** |
| --- | --- |
| **Annotations removed during bulk re-image** | If annotations were applied to the Image view, a bulk re-image will override these annotations if the below settings are checked when submitting the image job. ![Settings options for document overwriting, highlighting specific overwrite choices available.](https://cdn.us.document360.io/3e21d801-ca9f-4c51-93db-9cbd32741f3d/Images/Documentation/RENT_Bulk-Image-Job-Fix_2026.2(1).png) |
| **Document contains no indexable text** | The document exists in the project, but no searchable text could be extracted during indexing. Common reasons include non-text searchable PDFs, image based files, 0KB files, corruption, or encryption. |
| **Source file not found during indexing** | The source file could not be located or accessed during indexing. The most common reason is incorrect file paths. As a result, it’s text could not be extracted for searching purposes. |
| **Source file was too large to index** | The file is larger than the size limits set within the Text Set settings. It’s recommended to download and view these files natively. |
