URL Picker items with PDF media not working (and without media the URL picker item name is not carried over)

[imranhaidercogworks]

Describe the bug
We have a content page that has a block using multiple (80+) URL picker items picking a PDF from media.

• When publishing this page to a different environment (with media) we get an error:

Error while processing Push - (import/Media/1/). Upload fail: InternalServerError Internal Server Error : 33d21831-8ed8-4985-9fbf-54f1b2cc1e2d -
at uSync.Publisher.Publishers.SyncPublisherBase.UploadFile(String url, Stream stream, uSyncCallbacks callbacks)
at uSync.Publisher.Publishers.SyncRealtimePublisher.PushRequiredMedia(PublisherActionRequest request)
at uSync.Publisher.Services.SyncPublisherActionService.PerformAction(PublisherActionRequest request, ISyncPublisher publisher, IUser user)

• When publishing this page to a different environment (without media) it works but the data on the destination environment isn't the same as the source environment. Specifically the name given to the picked URL/Media item

Version (please complete the following information):

• Umbraco Version:13.8.0
• uSync Version v13.2.7
• uSync.Complete Version v13.1.10

To Reproduce
Steps to reproduce the behavior:

1. Create multiple URL picker items pointing to PDFs from Media
2. Give custom names on these items
3. Save and publish
4. Click on actions > publish to > target environment

Expected behavior
The page to be published to the target environment with all the media and the item names working

Hi,

Can you see any errors in the logs on either the source server or the target (the one getting pushed to). Its likely that the "internal server error" is what the target server is returning during the upload, so would be good to see if that has any errors.

It's also possible to get an error at this point from a firewall/proxy/etc. because the uploadFile method is POSTing a application/zip file to the server and we have seen firewall/proxy setups that block this (either for virus checking or just because they don't like people posting zip files to servers).

worth checking that, and if it can be modified for the uSync urls (https://docs.jumoo.co.uk/usync/complete/reference/connection#2-firewall-issues)
