When I upgrade NuGet version of Amazon.CDK.Lib from 2.97.1 to any higher version I get sts:AssumeRole related issue

[AleksandrsJakovlevsVisma]

Basically, the command npx cdk synth -o dist --app "dotnet run --project MyProject.csproj" App-* used to work, and when I upgraded the version, without changing anything else, I start getting these kind of errors:

[Error at /App-MyApp] Could not assume role in target account using current credentials (which are for account ACC1) User: arn:aws:sts::ACC1:assumed-role/Foo/Bar is not authorized to perform: sts:AssumeRole on resource: arn:aws:iam::ACC2:role/cdk-hnb659fds-lookup-role-ACC2-eu-west-1 . Please make sure that this role exists in the account. If it doesn't exist, (re)-bootstrap the environment with the right '--trust', using the latest version of the CDK CLI.

I solved it by:

1.) Running the cdk synth command with --no-lookups argument
2.) This resulted in the new error msg, listing missing values in the cdk.context.json
3.) I then manually added those missing values in the cdk.context.json file
4.) --no-lookups argument needs to be kept for some reason, otherwise the command fails
