Error when sending lookupPackageUris request

[helin24]

In a previous version of the Flutter Intellij plugin (65.0), we tried using lookupPackageUris to map breakpoints. This did not work when running an app in Chrome - the error the plugin received was:

{"code":-32603,"message":"lookupPackageUris: NoSuchMethodError: Class 'String' has no instance method 'toJson'.\nReceiver: \"package:hello_flutter_external/main.dart\"

/cc @bkonyi Looks like the problem happens after the response is returned from dwds - should I redirect this to you? It seems that the problem is in VmServerConnection that dwds uses. Dwds responds with a UriList but it fails to convert to json.

Ah, I see now. The list of URIs should be List<String?> but is List<dynamic> instead, so the code generator is likely just assuming there's a toJson() method present.

Fixed in SDK repo. @helin24 pub upgrade should pull the new version of package:vm_service that works with the existing dwds. Please let me know if there is still a problem!

Closing as fixed, please feel free to reopen if you encounter any issues.
