Hi, I finished adding notes APIs and I cannot deploy any of the functions. I’m have installed following versions:

node 16.3.0  
awscli 2.2.12  
aws-iam-authenticator 0.5.3

These dependencies in package.json:

“devDependencies”: {  
“aws-sdk”: “^2.927.0”,  
“serverless-bundle”: “^1.4.0”,  
“serverless-dotenv-plugin”: “^2.1.1”,  
“serverless-offline”: “^5.3.3”  
},  
“dependencies”: {  
“uuid”: “^7.0.3”  
}

This is the error I’m getting when I run serverless deploy command::

Wow, I fixed it. I started solving deprecation messages and just switched imaRoleStatements to iam.role.statements and it worked. I also added useDotenv: true, but don’t think that has to do anything with this.
