This looks like the screen where a pdf file loads in browser to show the contents: even file name is there! So are you able to download the document but opening is showing this screen or you get this screen as soon as you click on the download link?
Yes It is Chrome browser not able to load the pdf, if the content-type is set to pdf while uploading the doc to s3, loading of doc fails in Chrome so the fix is to set the content-type= application/pdf while uploading.Also I hope Appian add 'responsecontentdisposition' parameter to getPreSignedURLForS3 function to force the download of the documents always instead of loading the document.Thanks
Are you displaying the presigned URL as a hyperlink which on clicking displays the document in the web browser or you are using the URL to download the document?
Ideally we would want the documents to download directly instead of displaying for consistency. But chrome opens images, pdf in new tab but downloads docs like word, excel etc.
For that you can use the presigned URL to download the document. Pass the presigned URL as base url to an integration and it will download the document.
Yes thats an option but we using presignedUrl on a!safelink object to let users click and download from the grid, coz of that the download behavior is inconsistent for different file formats of the files residing in s3 buckets.Plz let me know if you have a remediation or work around it.Thanks
We are also using this for the first time. So far, we didn't face any file download issues. Can you please let me know the file extensions for which you faced issues?
