Build failing with not being able to restore workerExtension.csproj

Question

Hi, We are encountering a transient error in our cloud build pipeline. When attempting to restore packages for our Azure Function, we receive the following errors:

D:\dbs\sh\aac6\temp\0mjoggt1.c2j\WorkerExtensions.csproj : error NU1301: Unable to load the service index for source https://api.nuget.org/v3/index.json.
D:\dbs\sh\aac6\temp\0mjoggt1.c2j\WorkerExtensions.csproj : error NU1301: Unable to load the service index for source https://api.nuget.org/v3/index.json.
D:\dbs\sh\aac6\temp\0mjoggt1.c2j\WorkerExtensions.csproj : error NU1301: Unable to load the service index for source https://api.nuget.org/v3/index.js
on.

We had tried the hack as mentioned in https://github.com/Azure/azure-functions-dotnet-worker/issues/1252 to have seperate project adding the required dependencies and it had worked. However, the problem has resurfaced in the past two weeks. Could someone please assist us with this issue?
