Hi @msaravanaganesh,

Good morning.

Thanks for posting the issue. Looks like the script is unable to configuring .NET CLI AWS Lambda deployment tools and the error is thrown at https://github.com/aws/aws-lambda-dotnet/blob/04a0249fe10e1beb32fe0e73d7aa10f93ba25ccb/PowerShell/Module/Private/_DeploymentFunctions.ps1#L402

The exception is thrown after executing command to install/update .NET Global Tool Amazon.Lambda.Tools. Could you try running the Publish-AWSPowerShellLambda as an Administrator along with -Verbose flag and see if it works? You could also try executing command dotnet tool update -g Amazon.Lambda.Tools separately and see if it succeeds (since this is the command which is having issues, may be due to privileges).

Thanks, Ashish

Hi @ashishdhingra

Thanks for your reply, I had tried to publish the lambda function as administrator bust still getting the same error.

I tried update the AWS.Lambda.Tools with the given command "dotnet tool update -g Amazon.Lambda.Tools" but that fails

dotnet tool update -g Amazon.Lambda.Tools C:\Users\u107524\AppData\Local\Temp\x0dk5kcl.1yn\restore.csproj : error NU1100: Unable to resolve 'amazon.lambda.tools (>= 0.0.0)' for 'net6.0'. C:\Users\u107524\AppData\Local\Temp\x0dk5kcl.1yn\restore.csproj : error NU1100: Unable to resolve 'amazon.lambda.tools (>= 0.0.0)' for 'net6.0/any'. Tool 'amazon.lambda.tools' failed to update due to the following: The tool package could not be restored. Tool 'amazon.lambda.tools' failed to install. This failure may have been caused by:

• You are attempting to install a preview release and did not use the --version option to specify the version.
• A package by this name was found, but it was not a .NET tool.
• The required NuGet feed cannot be accessed, perhaps because of an Internet connection problem.
• You mistyped the name of the tool.

Still struggling to fix, I hope I tried all the possibilities, created a AWS case too but they also suggest to work in the gitHub

Hi @msaravanaganesh

I was having the exact same problem, and found a solution here on the Microsoft forums - Dotnet fails to install tools

running dotnet nuget list source showed an empty source list, and then running dotnet nuget add source https://api.nuget.org/v3/index.json -n nuget.org to add the default nuget source

After that I was able to run dotnet tool update -g Amazon.Lambda.Tools and the Publish-AWSPowerShellLambda I was trying

Hope that helps

Amazing yes it worked.

But any idea how and what happen suddenly end up .Net issue.

the same system was working earlier without any issues.

@msaravanaganesh Now that I can't explain, mine was a fresh install of the .Net SDK and the problem was present there
