AutomationTool exiting with ExitCode=25 (Error_UnknownCookFailure)

[Ore_Creative]

When trying to build out for Windows 64 bit (or anything else) the packaging fails with this error. AutomationTool exiting with ExitCode=25 (Error_UnknownCookFailure)

Thoughts?

Hi,

I have a few questions:

• Are you able to package a clean, blank project successfully?
• Would you mind providing your dxdiag?
• Are you using any delegates or event dispatchers in your project? The reason I ask is because I came across this thread where a user had the same error message that I see in your logs: Getting an warning in the log that I need to understand a bit better - Blueprint - Unreal Engine Forums

Thanks!

Alrighty, here we go.

• I’m not aware of how to start a new
  project using a custom engine version
  so I created a project in 4.13 and
  used the FPS template. Then I
  switched its engine version to the custom
  one I’m using and opend it. After
  that I complied it, and it failed with
  the same error. AutomationTool
  exiting with ExitCode=25
  (Error_UnknownCookFailure). Here’s the
  output log for that build as well.
  Output log FPS Temp

• DXDiag

• We are definitely using event
  dispatchers in our blueprints, but it
  would be time consuming to go through and edit them all to use interfaces (I will if I have to though), and since the FPS temp failed with the same error that might not been the problem.

Edit 1/7/17: I just built a clean version of unreal 4.14.2 and tested the fps template build so I know its not an issue with visual studios and its associated files. Witch leads me to believe its the custom toon shading model we are incorporating. That being said tracking down the error would be extremely helpful in moving forward.

Edit 1/8/17: I attempted to build our game project out on 4.14.2 and it failed with the same error which lets me know that the problem is not with the toon shader but with the project itself.

Any Ideas?

[Sean_L]

Sorry for the delay.

I see this error in your log: LogPluginManager:Error: This project requires the ‘LowEntryExtStdLib’ plugin. Install it and try again, or remove it from the project’s required plugin list.

Recommend going into the .uproject file using something like Notepad ++ and setting that plugin’s dependency to False.

That’s the only error that I’m seeing in your FPS Temp Output Log file that you’ve provided.

[Ore_Creative]

No problem.

I didn’t remove it it from the list but I did set it as false before I compiled. I’m getting the feeling that this is an unknowable error… Is there anything I can do to get more information about why this is happening? If not, I have to move the project over to newer version piece by piece and that’s going to take a solid week to do, and is not a sustainable way to handle bugs (if this happens again).

You could check this log file: D:\Custom Engine Folder 4.14.2\Engine\Programs\Automatio
nTool\Saved\Logs\Cook-2017.01.06-14.17.37.txt

However, I believe it’s possible that that particular plugin was not disabled correctly if it is still throwing that error message. Did you make sure it was disabled both in the editor and the .uproject file when you edited it with Notepad ++ or a similar program? Have you ensured the project’s Plugins folder doesn’t contain the LowEntry folder?

• Did you make sure it was disabled
  both in the editor and the .uproject
  file when you edited it with Notepad
  ++ or a similar program?

Yeah, I made sure it was disabled in both places (I just double checked to make sure).

• Have you ensured the project’s
  Plugins folder doesn’t contain the
  LowEntry folder?

Its was deleted at some point before I compiled.

Okay, so after looking over your initial project logs, there are quite a few errors that require attention. Here’s what I’d recommend:

Go through your log and CTRL+F “Error”. This will pop up all of the results and you can go through each one and look into resolving them. When I do this on your original log from the original question, I get 183 results, so I’d recommend taking a look through these and once you resolve each give packaging another shot to see if that resolves the issue.

The reason I suggest this is because there are no specific errors that stand out, and all of the errors need to be resolved in order for the packaging process to complete successfully.

Well, I’ve tested this out with epics starter content project and I still get the same AutomationTool exiting with ExitCode=25 (Error_UnknownCookFailure), and that’s with 0 project errors (for the xbox one version). Windows version builds fine. I’m using the toon shader model (engine build) as my base and it has worked before for xbox one builds. I’m trying to narrow the issue down to see if its the toon shader. So at this time I’m doing a clean build of unreal 4, with the standard xbox one files, running on epics starter content, and if that does not work, then there’s either a bug in the engine, xbox one files, or something wrong with my system. Here’s the link to the xbox one error.

[Sean_L]

Unfortunately, we cannot provide support for custom engine builds if it comes down to it being an issue with the shader or just the custom version in general.

However, if you are able to reproduce the issue in a clean project using a vanilla version of Unreal, feel free to leave a comment and provide your logs again and I’ll be glad to take another look.

Let me know what results your investigation yields.

[anonymous_user_bb2c1c15]

Sounds good,

We appreciate the assistance Sean. I’ll let you know how the clean build goes.

[Ore_Creative]

(Error_UnknownCookFailure) could be caused by a wide range of things. Try some of the suggestions found here. Make sure you have no errors or warnings. If those things don’t work stat a new help post and include your output log.

go to your plugins folder in your project Directory and remove any plugin’s folder that you disable it in unreal. it solved for me. test it. please remove all of extra plugins that you don’t want.
if didn’t work ? change your package directory and try to package in another Dir.
