Hello ; While waiting for someone from the @[UserSupport](https://easyeda.com/UserSupport) team to give an explainantion I suggest you to check the following guide : [https://docs.easyeda.com/en/Import/Import-KiCAD/index.html](https://docs.easyeda.com/en/Import/Import-KiCAD/index.html)

Your zip file missing library, you need to compress it at Kicad, not compress the folder directly.

Here is another one for you to check, I have included everything (Not working) [https://www.dropbox.com/s/gi8twgcikb4a53i/512.zip?dl=1](https://www.dropbox.com/s/gi8twgcikb4a53i/512.zip?dl=0) (Working) [https://www.dropbox.com/s/a20rquh07kztsk2/5122.zip?dl=1](https://www.dropbox.com/s/a20rquh07kztsk2/5122.zip?dl=0)

@[dillon](https://easyeda.com/dillon) I  think you will have an idea how this works, because you are working on file formats. I just want to understand what is wrong with the "Not working" file. I have done a text compare between the two projects I haven't seen any glaring differences.

Issue confirmed, it is importer's bug. I will add it to bug list. Thanks

Do you know what is the root cause? I just want to know if I could do something on my end. This is the only thing that I could gather from my end `{` `    "success": false,` `    "message": "Unexpected error while converting.
