After publish Blazor app I get error "Invalid object name"-CodePudding

I have a Blazor application (Wasm), ASP.NET hosted (.net 5). When debugging everything works fine. But if I publish the application and run the compiled EXE, I get the following error. I am using two databases in the application and the error mentions the second one. Could someone point me in the direction of what the problem is? Connection strings are set the same for debugging and publishing versions.

Thank you for your help.

Update: In both cases, the appsettings.json are the same, except for the IdentityServer section. There I added a Key section (link to the certificate).

// appsettings.json
{
  "ConnectionStrings": {
    "DefaultConnection": "Server=testmachine;Database=vks;User=myUser;Password=myPasswd",
    "AISConnection": "Server=testmachine;Database=ais;User=myUser;Password=myPasswd"
  },

    "LogLevel": {
      "Default": "Information",
      "Microsoft": "Warning",
      "Microsoft.Hosting.Lifetime": "Information"
    }
  },
  "IdentityServer": {
    "Key": {
        "Type": "Store",
        "StoreName": "My",
        "StoreLocation": "CurrentUser",
        "Name": "CN=VksCertificate" 
    },

  },

CodePudding user response：

Thank you all for the advice and although it's embarrassing, I'll put the solution to my problem here. I didn't notice that after publishing the app, three appsettings files (appsettings.json, appsettings.development.json, appsettings.production.json) are created in the folder publish and that was my problem. I had the wrong database name in the appsettings.production.json file. I have no idea why, I didn't know about this file at all.
