Thumbnail generation for items in DSpace 7.5 is not working

[Lucas Silveira]

Dear Collegues,

I am working with DSpace 7.5 and facing difficulties in generating thumbnails for approximately 50,000 items. I have tried generating thumbnails using the "./dspace filter-media" command, but without success. Subsequently, I attempted to generate thumbnails for each collection using the "./dspace filter-media -i handle" command and executed the "./dspace index-discovery -b" command, but still, I did not succeed. I have not made any changes to the variables in the dspace.cfg file. Does anyone have any suggestions or know where I might be going wrong? I appreciate your help in advance.

Hello, I had to do it manually until I enabled the solr text indexing, I can't say why but it sarted to create thumbails from images and pdfs. 

Note that Dspace indexes by default the uploaded files at 3 AM, is possible to change it. So when you upload a file, the next day you will see the thumbnail. I hope this helps!

Thank you, Mercedes. I found the issue. I am migrating the digital library from version 6.3 to 7.5. The migration changed the access policies, and when I logged in, the thumbnails became available. So, I just need to adjust the access policies to make them available for anonymous users, and everything will be fine.

First suggestion: tell us how it is failing. What error messages did
you see on the console? Are there relevant messages in the log?
