am getting this error in NetSuite. The media item you selected is not available for preview. This error is shown when i click on preview on a pdf file shown in file field

AI generated answer (using internal Slack threads):

The error message you're seeing, "The media item you selected is not available for preview", typically occurs when NetSuite is unable to locate the file you're trying to preview. This could be due to a few reasons: 1. The file has been moved or deleted from its original location in the file cabinet. 2. The file URL is hardcoded in your SuiteScript and the URL has changed, especially if you're working in a Sandbox environment. The account ID in Sandbox is different from the production environment, which could lead to broken links. 3. There might be an issue with the file itself, such as corruption or unsupported format. To resolve this issue, you can try the following steps: 1. Verify the file's existence in the file cabinet and its location. 2. If you're working in a Sandbox environment, check your SuiteScript for hardcoded file URLs and update them to reflect the correct Sandbox account ID. 3. If the file is a PDF, try opening it with a different PDF viewer to rule out issues with the file itself. ****** Disclaimer: This response was generated by an artificial intelligence assistant based on previous conversations from multiple Slack channels, and may contain inaccuracies or mistakes. ******
