How to fix Git push error: "RPC failed; curl 56 HTTP/2 stream 7 was reset send-pack: unexpected disconnect while reading sideband packet fatal: the remote end hung up unexpectedly"

Problem

Today I saw the following problem when I tried to push my changes to a Git server after doing some work for upgrading an Umbraco v7 project to v8.18.8. 





Possible reasons

After some investigations, it seems like this could be because of the following reasons;

  • Git is not happy with the amount of changes that are being pushed into the server. 
  • There are possible limitations on the server about the size/amount of files that you can push.
  • Your internet connection is not good and stable enough.
  • Your Git client's version is old.

Solution options

For me, the easiest option was connecting to another Wifi and trying again. Apparently, this option helped quite a few people, so it is worth giving it a try. Unfortunately, it didn't work for me. A bad internet connection wasn't an option for me either, as my internet is pretty fast (500 Mbps). Similarly, my Git client version was the latest version (git version 2.41.0.windows.3). 

On StackOverflow, there were a lot of recommendations to set the http.postBuffer to something higher.  

I tried this option, too. Once more without any luck. After digging into more details about setting the postBuffer, I learnt that Microsoft recommends not doing this blindly without reviewing this article first that recommends upgrading the Git client to the latest version, checking some hotfixes and things like whether you are using a proxy or load balancer. In this same article, it also states the following;






How I fixed my issue

After trying all these options, I ended up pushing one small change at a time and that worked like a charm. This way I didn't need to make any changes with my current setup.

If you have started working with Umbraco v9 and done your first Azure deployment to one of your testing environments, there is a possibility that you might see the following "Boot Failed" error.

How to use JQuery Ajax Methods for Async ASP.NET MVC Action Methods

Making repeatedly calls to async methods can be a nightmare. In this case, it makes sense to use 2 ajax methods, instead of one. Here is a simple solution to overcome this problem. See that  ajaxcalls   is emptied after the success response for the first ajax call and then the second ajax method is used to make one single call to the async action method. Hope it helps. View: @section Scripts{     < script type ="text/javascript">         var smartDebitObject = new Object();         smartDebitObject.MembershipNumber = $( "#MembershipNumber" ).val();         smartDebitObject.ProfileId = $( "#ProfileId" ).val();         smartDebitObject.FirstName = $( "#FirstName" ).val();         smartDebitObject.LastName = $( "#LastName" ).val();         smartDebitObject.AddressLine1 = $( "#AddressLine1" ).val();         smartDebitObject.Postcode = $( "#Postcode" ).val();         smartDebitObject

How to fix Umbraco CMS Build Error NU1104: Unable to find project '..\Umbraco-CMS\tools\Umbraco.Core\Umbraco.Core.csproj'.

Yesterday during an online meeting , I was talking about how to contribute to Umbraco CMS . As part of this talk, in order to set up my local Umbraco CMS project ,  I cloned the latest Umbraco.CMS code to my local machine, but when I built it I saw the following error: Error NU1104 Unable to find project ' D : \git \repos \Umbraco -CMS \tools \Umbraco .Core \Umbraco .Core .csproj ' . Check that the project reference is valid and that the project file exists . Umbraco .JsonSchema D : \git \repos \Umbraco -CMS \tools \Umbraco .JsonSchema \Umbraco .JsonSchema .csproj I was surprised to see this error as I did the exact same thing a couple of days ago and saw no problems.  After trying a few things, I checked the Umbraco.JsonSchema project's project references and realised that Umbraco.Core project reference was broken.  After removing Umbraco.Core from the Umbraco.JsonSchema and adding it again fixed the problem and I could then do my local database setup as normal.
