Why isn't my CDK Lambda function running the pip install command?

I've set up several Lambda functions in my CDK code, and while some work perfectly and run the bundling command, one of them isn't functioning as expected. The functions are very similar—aside from the names and a few environment variables—but this particular one isn't installing any of the required imports. It deploys without any errors, but the packages just aren't there. Here's the code for the problematic Lambda function: ```javascript const collectionLoader = new lambda.Function(this, "CollectionLoader", { code: lambda.Code.fromAsset( path.join(__dirname, "../src/collection_loader"), { bundling: { image: lambda.Runtime.PYTHON_3_12.bundlingImage, command: [ "bash", "-c", "pip install -r requirements.txt -t /asset-output && cp -au . /asset-output", ], }, }, ), environment: { MAX_ATTEMPTS: "5", BUCKET_NAME: dataBucket.bucketName, DLQ_URL: dlq.queueUrl, }, handler: "handler.lambda_handler", runtime: lambda.Runtime.PYTHON_3_12, vpc, securityGroups: [privateSG], timeout: cdk.Duration.seconds(300), }); ``` I also included the code for a function that works fine: ```javascript const otherFunction = new lambda.Function(this, "OtherFunction", { code: lambda.Code.fromAsset( path.join(__dirname, "../src/other-function"), { bundling: { image: lambda.Runtime.PYTHON_3_12.bundlingImage, command: [ "bash", "-c", "pip install -r requirements.txt -t /asset-output && cp -au . /asset-output", ], }, }, ), environment: { DIFFERENT_ENVIRONMENT_VARIABLE }, handler: "facets.handler", runtime: lambda.Runtime.PYTHON_3_12, vpc, securityGroups: [privateSG], timeout: cdk.Duration.seconds(300), }); ``` I'm struggling to figure out why the packages aren't being installed and would appreciate any insights!
