Creating a zip file for my Lambda

Question

Hello! I wanted to ask if you could provide some insights into an error I am running into when I run the command line below to create a zip file for my lambda?

Command line: **dotnet lambda package --configuration release --framework net6.0 --output-package releases/test.zip**

Error: *The type or namespace DynamoDBv2 does not exist in the Namespace 'Amazon' (are you missing an assembly reference)?*

I am following the steps from the documentation linked: https://docs.aws.amazon.com/amazondynamodb/latest/developerguide/CodeSamples.DotNet.html

I have installed the NuGet pkg: AWSSDK.DynamoDBv2 (3.7.301.20) numerous times, and each time I run the command line after, then I get the error and my NuGet pkg is still there but there is now a warning icon over it.

I've ran the command line before in the past with other AWS resources like SQS, so I am not sure why the error is occurring.

Hello, I will try that and provide an update.

Is the `AWSSDK.DynamoDBv2` package is installed in the Lambda project itself? It's important that the package is referenced directly by the project being packaged. If it's only included in a dependent project, ensure that the dependencies are correctly being resolved. Try to open your Lambda function's `.csproj` file to verify that the `AWSSDK.DynamoDBv2` package reference exists:

```xml

```
If it's missing, add it manually or re-install the package using the command line: 
```sh
dotnet add package AWSSDK.DynamoDBv2 --version 3.7.301.22
```
Before running the `dotnet lambda package` command, make sure all `NuGet` packages are restored properly to resolve any missing dependencies:

```sh
dotnet restore
```
