Content conversion error


We are trying to perform bulk upload of files to Alfresco repository using CMIS API. But after certain point of time getting the below error.

Content conversion failed:mimetype=application/vnd.openxmlformats-officedocument.spreadsheetml.sheet, size=20446, encoding=UTF-8, locale=en_US

Re: Content conversion error

This seems to be issue with file transformation. Alfresco does file transformation for preview and thumbnail for every file. I suspect this issue is related to that. You may want to check following link,

Large ppt file can not previewed 

Could not load PDF content  


I hope this will be helpful to research further


Re: Content conversion error

Conversions can fail for a myriad of reasons. Check catalina.out to find out what exception is being thrown and that should give you a clue.

This shouldn't be causing your CMIS upload to fail because out-of-the-box transformations for thumbnails occurs asynchronously. Have you created a rule or behavior that is forcing a transformation?
