issue: 1- Create New Project: abp new Demo -t microservice-pro -u blazor 2- Go to services\product\src\Demo.ProductService.HttpApi.Client folder 3- Edit ProductServiceHttpApiClientModule.cs, change AddStaticHttpClientProxies to AddHttpClientProxies 4- Run project, login into blozor site and click on the products tab, see the error. 5- Interestingly when you add new remoteservice path addresing the Product Service Host domainname to the appsettings file of the master blazor project, blazor site starts working. But with this method, you simply bypass the web gateway and directly communicate with product microservice. 6- Another note, updating c# client proxies using cli even does not run, gives error. So using static proxies is not on the table. Here is the error stack trace; abp generate-proxy -t csharp -u http://localhost:44361/

7- I need to run blazor site with my dynamic proxied micro services. 8- Another issue is that when you set up a new project as described in step 1, and run the blazor site, app welcomes you with an error dialog. You can simply click ok to continue, but it is also annoying. Error says: Could not find 'afterLeptonXInitialization' 9- I hope you can suggest a quick solution for the problem, it took days for me to upgrade the entire solution, and I dont wish to rollback.

I have figured out the proxy problem. I added reference to product api project and inserted following code to the gatewaymodule.cs
app.MapWhen( ctx => ctx.Request.Path.ToString().StartsWith("/api/abp/api-definition") || ctx.Request.Path.ToString().TrimEnd('/').Equals(""), app2 => { app2.UseRouting(); app2.UseConfiguredEndpoints(); } ); app.MapWhen( ctx => ctx.Request.Path.ToString().StartsWith("/metrics"), app2 => { app2.UseRouting(); app2.UseHttpMetrics(); app2.UseConfiguredEndpoints(endpoints => { endpoints.MapMetrics(); }); } );It fixed the issue.
Issue stated at step 8 can be answered. I still get the "Could not find 'afterLeptonXInitialization'" error on first run.

Hi,
ABP Framework doesn't support dynamic proxies in microservice projects. As you mentioned above, it comes with the static proxy by default.
Also, we'll try to reproduce the

Hi Malik,
After a bit of work, dynamic proxies works as expected. I somehow managed to run microservices with dynamic proxies.
I will be glad if any solution for afterLeptonXInitialization error is supplied.
Thanks in advance. Regars.

afterLeptonXInitialization
For
afterLeptonXInitializationissue, it seems the leptonx javascript bundle is old. afterLeptonXInitialization logic was included in LeptonX v1.0.0. Make sure your LeptonX dependencies are equal or above1.0.0in.csprojandpackage.jsonfiles.Then run following command for MVC and Blazor-Server projects.
abp install-libsIf your project is Blazor WASM, try following one
abp bundle -
