lately, every time I run the setup:upgrade command, I notice that inside the "theme" table all the parent_id are overwritten and set to 1 (magento blank).On backoffice side, the themes are shown with the right inheritance and also inside the theme.xml file of the child themes, I don't see particular problems.
here is an example of the theme.xml file of a child theme:
<theme xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="urn:magento:framework:Config/etc/theme.xsd"> <title>Theme4 - Magento 2 Theme</title> <parent>custom_theme/theme1</parent> <media> <preview_image>media/preview.jpg</preview_image> </media>
in the last year it has always worked. I've been getting this error for a couple of days. I think due to activity on the machine. at the moment I don't know what could be the causes for which the parent_id are set to 1
