How to determine "Version" of existing report when using REST API

When trying to update a file resource on the jasper server using the endpoints described here: https://community.jaspersoft.com/documentation/tibco-jasperreports-server-rest-api-reference/v710/working-file-resources#Updating_File_Resources it requires a "version" of the report in order to update it and if you don't have it you will get an error back. I tried using the "overwrite" option but it still requires the version. Is there a way to get the version of a file on the server through the REST API? If so which endpoint, and where in the returned data can I find it?

Hopefully this helps someone in the future. If you use this endpoint: https://community.jaspersoft.com/documentation/tibco-jasperreports-server-rest-api-reference/v710/resources-service#Searching_the_Repository it will return the attributes of the file, including the version of the existing file. The problem is that it's a search endpoint so you have to be really specific about the file that you are wanting otherwise it will return a list of files. Use fileUri= and q= options to pinpoint to the exact file you want info for.

Note that this endpoint: https://community.jaspersoft.com/documentation/tibco-jasperreports-server-rest-api-reference/v710/resources-service#Viewing_Resource_Details Will return the object that you uploaded. Which, in my experience, if the file is a jrxml file it will return the actual jrxml file and it doesn't actually include the attributes of the file on the server (which is where the version is at).
