I am not getting correct ModifiedOn date from getcontentobjectrevisionhistorydetails

I'm not 100% sure but it looks like there is some manipulation being done outside the actual plugin function as the getcontentobjectrevisionhistorydetails function has "Date Created" and "Date Updated" and not a "modifiedOn" field. Given that you're getting the most recent version before the current one my guess is that whatever code is surrounding the function isn't using the Version Id correct.

So, a bit of a stab in the dark but maybe your code isn't considering the current version as having a Version Id of -1? See below for the raw format from the getcontentobjectrevisionhistorydetails function.

[ Version Id, Date Created, Date Updated, Size (Bytes), Author],
[ -1, 2025-02-13 05:10:13.0, 2025-02-13 05:10:13.0, 3176, authorUsername],
[ 7, 2025-02-13 00:20:35.0, 2025-02-13 00:20:35.0, 2854, authorUsername],
[ 6, 2025-02-13 00:20:19.0, 2025-02-13 00:20:19.0, 3036, authorUsername],
[ 5, 2025-02-13 00:14:49.0, 2025-02-13 00:14:49.0, 2306, authorUsername],
[ 4, 2025-02-12 05:51:49.0, 2025-02-12 05:51:49.0, 2501, authorUsername],
[ 3, 2025-02-12 05:40:21.0, 2025-02-12 05:40:21.0, 2319, authorUsername],
[ 2, 2025-02-12 05:25:05.0, 2025-02-12 05:25:05.0, 1904, authorUsername],
[ 1, 2025-02-12 05:07:48.0, 2025-02-12 05:07:48.0, 0, authorUsername], 

If this is totally off the mark can you provide the code you are using?

Hi Andrew, Thanks for replying. sry for that i missed one point here, its not getcontentobjectrevisionhistorydetails, its getappobjectuuids where we can get modifiedOn field, and as you mentioned above i am considering version Id -1 as well, you can see for i got one version for one object 
"{"versionId":" -1","createdDate":" 2025-02-06 10:08:37.0","updatedDate":" 2025-02-06 10:08:37.0","size":" 2783","author":" Balavamsikrishna_Vinnapala@contractor.amat.com"}

Could you please check with getappobjectuuids on my above query 

Ah! Ok. The getappobjectuuids function is from a different plugin than the Appian developed "Content Tools" plugin. The top comment in the "Get Application's Content Objects" plugin ( Get Application's Content Objects ) is below and it seems like this is just an error with the plugin. Given it's nearly 5 years old, and plugins aren't supported by Appian, it seems like it just isn't going to do what you need.

Personally I try to limit my use of non-Appian developed plugins. It's unavoidable sometimes but if I can achieve what I need to another way, even if the plugin is more convenient, I'll choose the supported path. Even though Appian doesn't support any plugins I feel much more comfortable using Appian developed ones.

Like Andrew mentioned, I would recommend you use the Content Tools plugin to get the information you need. If you found a bug with the plugin you are currently using, you should try to contact the plugin author.

How can i contact to the Plugin Author Andrew Hickingbotham Mathieu Drouin
