cdktf: Synth ignore code changes and generate with old values

Expected Behavior

I had an Lambda function from a generated module and change name of handler attribute from mail.handler to index.handler. I also add a Policy attachment. So it should change the handler property and create new policy.

import {Construct} from 'constructs';
import {LambdaFunction} from '../.gen/modules/lambda-function';
import {AssetType, Fn, TerraformAsset} from 'cdktf';
import * as path from 'node:path';
import {DataAwsIamPolicyDocument} from '@cdktf/provider-aws/lib/data-aws-iam-policy-document';
import {IamPolicy} from '@cdktf/provider-aws/lib/iam-policy';

export interface EmailExtractorConfig {
    readonly extractedBucketPath: string;
    readonly inboundBucketPath: string;
    readonly functionArtifactPath: string;
}

export class EmailExtractor extends Construct {
    private readonly lambdaFunction: LambdaFunction;

    constructor(scope: Construct, id: string, config : EmailExtractorConfig) {
        super(scope, id);
        const policy = new IamPolicy(this, `${id}-policy`, {
            name: "email-extractor",
            policy: new DataAwsIamPolicyDocument(this, `${id}-policy-document`, {
                statement: [{
                    effect: 'Allow',
                    actions: ['s3:GetObject'],
                    resources: [`arn:aws:s3:::${Fn.replace(config.inboundBucketPath, "s3://", "")}`],
                },{
                    effect: 'Allow',
                    actions: ['s3:PutObject'],
                    resources: [`arn:aws:s3:::${Fn.replace(config.extractedBucketPath, "s3://", "")}`],
                }]
            }).json
        })
        this.lambdaFunction = new LambdaFunction(this, "function", {
            functionName: 'email-extractor',
            roleName: 'email-extractor',
            runtime: 'nodejs20.x',
            handler: 'index.handler',
            filename: new TerraformAsset(this, 'lambda-asset', {
                type: AssetType.ARCHIVE,
                path: path.resolve(config.functionArtifactPath),
            }).path,
            ephemeralStorageSize: 1024,
            memorySize: 1024,
            publish: true,
            tracingConfigMode: 'Active',
            lambdaEnvironment: {
                variables: {
                    INBOUND_BUCKET_PATH: config.inboundBucketPath,
                    EXTRACTED_BUCKET_PATH: config.extractedBucketPath,
                }
            },
            customIamPolicyArns: [policy.arn]
        })

    }

    getLambdaArn() : string {
        return this.lambdaFunction.arnOutput;
    }
}

Actual Behavior

No changes detected

When i run cdktf deploy or cdktf synth in cdk.tf.json will sill be the old value "mail.handler". Also when I delete cdktf.out folder. I had no idea where the old value comes from. Maybe from remote backend?

Changes on Environment Variables are detected and will deployed.
