@git-acuratechglobal You need to actually include the output, otherwise it is unactionable.

The error message here comes from VS Code's LSP client and unfortunately the default behaviour is not very helpful - the "Output" it refers to doesn't actually contain any information about the failure (see Dart-Code/Dart-Code#5328).

In a recent update to the Dart-Code plugin, I override this error handling to provide a message which should end with "See the log for more information" and include a button to open the log file, which should contain useful information (for example any exception from the server).

@git-acuratechglobal can you confirm which version of the Dart extension you're using? If it's earlier than v3.106, then please upgrade to the latest one. If you're already on a later version, then you may be affected by microsoft/vscode-languageserver-node#1608 which seems to be a bug in the VS Code LSP client that prevents the custom error handler from being invoked. In that case, please try enabling the Analysis server instrumentation log and checking it for any exception after reproducing this issue (note: the log file will contain parts of your source code, so carefully review any parts you are sharing).
