Are you using iOS or Android version of the Collector?

Thanks

Hi Russ,

I am having the same problem. I have a map with 10 points and photo attachments I've collected and I am trying to sync it back to AGOL. Everytime I try and sync I get the following generic message "Sync Error - An error occurred while synchronizing edits". Any ideas???

I too am having this issue. With simple point features and photo attachments. I have 2 separate devices both having the exact same issue. The feature service is hosted on AGOL, I have ensured editor tracking is turned off. We're using Collector for Android on a Sony tablet. One device has 7 features stuck on it and the other has 27. We really need to get them off.

The upcoming update to the Android app has enhancements to support larger syncs and will help reduce the chances you are seeing these errors. Did you have multiple attachments associated with features with the data collected?

Thanks for your advice Russ. Some features had multiple attachments but not many. As mentioned in another feed i have instructed our users to try and sync back after every 5 features collected if they have phone service. I'm pretty sure this is the issue in regards to the device being an Android and a number of features being collected all with photo attachments.

We eagerly await the Android update.

I am having this error currently as well. I have 21 points with no attachments and am using Android. It will get up to 50% and then stop. Sometimes it will show as synced, but the features don't show up online and if I close and re-open Collector it shows I still need to sync the 21 points.

Hey Rachel,

Can you try this: First make a backup of the map having the issue. You can copy this data to another folder or locally to your computer. Then delete the client_delta geodatabase and the syncgdb_request folder. After you have deleted these items restart the app and try to sync again.

So, to clarify, you want me to back up on the map on AGOL? Where do I find

the client_delta GDB and syncgdb_request folders?

Have you found a solution with your sync issue? I am having the same issue on an Android with Collector 10.3. Did you find where these folders are?

Re: An error occurred while synchronizing edits

RussRoberts — Thu, 26 Feb 2015 21:10:34 GMT

If you are having sync issues you are use this tool:

Copy Runtime Geodatabase To File Geodatabase—Help | ArcGIS for Desktop

The folder that contains your map content is under ArcGIS_Collector >Offline_data>account folder> folder with same item id as your web map.

Copy that folder onto your desktop and run the tool against the data in that folder.

Awesome! Thank you! I have a bug report in to ESRI for our sync issues. Last I heard, our tokens are being truncated. They're looking into it. I will post when I hear more.

Hi Russ,

What happens after running the tool against the data ? Will it sync during this process or is there steps after that to complete the job.

Kind Regards

Re: An error occurred while synchronizing edits

RussRoberts — Mon, 30 Mar 2015 16:52:18 GMT

the GP tool will add all the data that is in the .geodatabase file to a file GDB. From there you can merge your data into the final dataset.

I have found the answer to my sync issue and thanks everyone for your input. Turns out, the inability to sync was due to an issue with our IIS 7 web server and arcgis web adaptor settings. In IIS, if you go to your web adaptor name, then the WebAdaptor folder, check out the UploadReadAheadSize setting. The default value was 41942, and ESRI told me to up it to 20 million. This solved the issue!

Funny, I went through a similar situation of chasing bugs and re-publishing different services last year which was finally resolved with the same solution Janice.

Hopefully people find these posts and save time, seems like it should be an earlier troubleshooting step in the ESRI ArcGIS Collector handbook!

Below is the step by step solution:

These are the instructions that ESRI provided on changing the uploadreadaheadsize:
Launch “Internet Information Services (IIS) Manager”
Select the site that you are hosting your web application under it.
In the Features section, double click “Configuration Editor”
Under “Section” select: system.webServer ,then select serverRuntime
5. Modify the “uploadReadAheadSize” section to be like 20MB (the value there is in Bytes)
6. Click Apply this is happening as during renegotiation step;
Hopefully this helps others!

And this is the similar thread: Offline works in ios but not android

Hi Russ, I have two files that I am trying to run the above mentioned Runtime tool on. The first file is a .geodatabase file that I had tried to sync with AGOL but had failed. The file was renamed by Collector to client_delta_x. I ran the Runtime tool and it worked perfectly. The second file is the rest of the data we collected after failing to sync. Unfortunately, during the time we were out collecting, the AGOL web map was deleted so we can't even try to sync it anymore. It was not renamed by Collector to client_delta_y and the Runtime tool does not work against that data when I run it. I get an Error 001730 message when I run it telling me it's likely not a .geodatabase file. It is however a .geodatabase file and is the same in all other regards as the file that worked, the only difference being that syncing wasn't attempted and the name of the file wasn't changed to client_delta. Any help would be greatly appreciated!

Russel,

Can you elaborate on how to merge the data back into the final dataset?

I've used the workflow you've suggested to create a FGDB from a couple days worth of field work that I cannot get to Sync. I now have a few FGDBs and need to merge them back into my SDE on our GIS Server. Is there documentation somewhere that explains these steps? It's important that global IDs, and related attachments are retained through the merge.

Thanks,

Jacqueline
