Error Saving custom Theme - Theme Designer - Fiori

Hello Guys, I´m trying to replace the SAP company logo with customer´s one using a copy of the blue Crystal theme, but when I press the Save and build option Ipm getting an error.

I´ve read another post with the same error.

We´ve upgraded our UI5 version (1.28.14) because it was too old and we've implemented all related notes. described in the note 2207373 - SAPUI5 upgrade to version 1.28.14

UI5 version.

Here are all the components installed in the Front-end Server.

Am I forgetting Something? because the error is still there.

Thank in advance for your help.

Regards

Diego.
