Server error: could not built target

Hi everybody:
I need help. I’m creating a new app and these last two days I have had problems with the generation of the apk file.
It seems that everything it’s ok in the code, because I can visualize the app with the Companion, but when I have tried to generate the apk, it appears the message: “Server error: could not built target. Please try again later!”.
I don’t know if there is any limit of multimedia files to include in the apps, and maybe it can be for this.
Thank you for your help.

What is the exact error in building apk?

And what is the size of your total assets ?

The error is what I wrote in the previous post “Server error: could not built target. Please try again later!”.
I have tried this during the last three days, several times, and the message is always the same.
I don’t know what is the size of my assets, but they are about 500 photos and 10 audio files.

Start deleting assets … too many !!!

Then, is there a limit of assets?
I didn’t know it.
What is the limit?
