Hi,

It seems that Radzen has created invalid launchSettings.json file. Can you please attach that file here so we can take a look?

The site does not permit me to upload files, here is the content of file:

{
“profiles”: {
“project”: {
“commandName”: “Project”,
“launchBrowser”: true,
“environmentVariables”: {
“ASPNETCORE_ENVIRONMENT”: “Development”
},
“applicationUrl”: “http://localhost:64117/”
}
}
}

That file looks valid from first sight. Can you zip the whole ‘server’ directory of your Radzen application and send it over to info@radzen.com? We will run it locally and see where the invalid JSON file is.

Best regards,
Atanas

Thanks! The problem is in the appsettings.json file. Unfortunately it is a bug with persisting the connection string when a data source has underscore in its name. As a workaround you can delete the existing Snak_CEP data source and create a new one called SnakCep.

We will fix that problem and release a hotfix build tomorrow.

Hi Marden,

We’ve just published Radzen 1.33.2 with fix for this problem included.

Best Regards,
Vladimir
