Hey @normjon, without more information I'm not able to help you. Can you tell me more about your problem?

[normjon]

I thought I provided details, but clearly I didn't. Here you go.

Example code giving error:
const role = new iam.Role(this, 'myRole', {
assumedBy: new iam.AccountPrincipal('1234')
});

Error description coming from IDE:
Type 'AccountPrincipal' is not assignable to type 'IPrincipal'.
Types of property 'principalAccount' are incompatible.
Type 'string | undefined' is not assignable to type 'string'.
Type 'undefined' is not assignable to type 'string'.

Error description for Class Role (role.d.ts):
Class 'Role' incorrectly implements interface 'IRole'.
Types of property 'principalAccount' are incompatible.
Type 'string | undefined' is not assignable to type 'string'.
Type 'undefined' is not assignable to type 'string'.

Let me know if more details are needed.

Thanks

Can you check your package.json to make sure all CDK related packages are the same version?

@peterwoodworth response worked for me when I got the following error: Type 'Role' is not assignable to type 'IRole'.
CDK dependencies installed after the initialisation had a higher version number than the core package. Set them all to the same version as the core package and it works (i.e. no errors).

Yup, that's the most common cause of this error, it's likely what happened to @normjon as well

@peterwoodworth Having an issue with this (using Python and CDKv2 in my case).

Error (using PyLance):

Argument of type "Role" cannot be assigned to parameter "role" of type "IRole | None" in function "__init__"
  Type "Role" cannot be assigned to type "IRole | None"
    "Role" is incompatible with protocol "IRole"
      "grant_pass_role" is an incompatible type
        Type "(identity: IPrincipal) -> Grant" cannot be assigned to type "(grantee: IPrincipal) -> Grant"
          Parameter name mismatch: "grantee" versus "identity"
    Type cannot be assigned to type 

Steps I've taken to mitigate, given feedback above:

1. Deactivate and delete my virtual environment
2. Updated my constraints.txt file with the following versions:

pytest==6.2.5
boto3==1.20.37
aws-cdk-lib==2.23.0
constructs==10.1.5
cdk8s==2.2.85
cfnresponse==1.1.2

3. Updated npm: npm update
4. Updated aws CLI: npm i -g aws-cdk
5. Created new virtual environment: python3 -m venv .venv
6. Activated my virtual environment: . .venv/bin/activate
7. Install requirements: pip install -r requirements.txt -r requirements-dev.txt -c constraints.txt

Still seeing this error :/. I'm not sure how the Pipfile plays into this, but would appreciate any clarification possible.

Also, please let me know if I should create a new issue :).

Can you try npm i -g aws-cdk@2.23.0?
