Flutter for Web - Error compiling dartdevc module:stock_notes|web/main.ddc.js #2362

cc @jensjoha any ideas on this one? |
It seems like we're trying to load an empty (i.e. 0-byte) file. |
|
Is there any better error message we can give here? On the build side, should we suggest folks clean and restart? |
|
I also wonder if we can detect this earlier - when we first see the empty output rather than when we try to give it as input. Can we assume that a kernel output should never be empty? |
Towards #2362 We don't know where the zero byte files are being introduced to the system - if they are coming from the kernel worker try to catch them earlier by checking for when we copy a file with no content. This won't solve the issue but if errors surface through this they should be more clear. - Add a `requireContent` argument to `copyOutput`. In the future we might consider making the default either with or without an output - we don't know of any use cases where we want to allow copying a zero byte file. - Use the new argument from the kernel builder to check earlier whether a kernel file is empty.

A kernel file should never be empty.
Maybe we should add some checks in the ddc and bazel pipelines to check up front both if the input is non-empty and the output is non-empty..? |

We haven't hit this, I think, for quite a while now. Probably because flutter web is no longer using @jakemac53 do you recall seeing any more recent reports of this issue from non-flutter users? |

I have not seen any recent reports |

Hi,
I've encountered an error while trying to run the page via
webdev serve --auto restartcommand, however, when I deploy the website to Firebase Hosting or simulate the hosting locally by executingFirebase serve --only hostingeverything works fine.The code that produces an error worked at first, then I made some changes that made the web app stop working. Thinking it was some error in my code I reverted the code to the last known working version, but it didn't work anymore.
I'm attaching an error message below:
