Hello 5v29n,
Packaging for this works without an issue for me so it must be something wrong locally. It seems that the error messages are being omitted from the logs, likely due to it being in another language and the encoding causing the information to be lost. Can you try packaging once more and copying the text directly from the Output Log in the editor? You can open the Output Log from Window > Developer Tools > Output Log. If you can find out what the actual error is, which looks as though it would’ve been displayed on line 518 in the first log you posted, please provide that, as Unknown Cook Error just means that the cook failed and doesn’t tell us any information.
