[Application Update Error] - The element 'Field' in namespace 'urn:deployment-manifest-schema' cannot contain text.

Question

Hello,
I developed a custom SharePoint 2013 Application (SharePoint hosted) and everything works fine. If I tried to update the application and I ran into the following error:
The element 'Field' in namespace 'urn:deployment-manifest-schema' cannot contain text. List
of possible elements expected: any element in namespace '##any'.
If I redeploy the application (without update, just a new instance) everything works fine. Only the update scenario throws the exception above. 
I tried different things to solve that issue:
I recreated the feature
I checked all the custom field definitions, content types and lists inside the app. 
I tried different O365 tenants and a SharePoint 2013 On Premise Development Server (Same problem on all systems)
Can anybody give me a tip to solve that problem?
Thanks in advance

Hi,
According to your description, when you try to update your SharePoint Hosted App, an error occurs.
To narrow down the issue, I would suggest you create a simple app without other components in it, deploy it and then update it to see if this error will still occur.
Once you get a workable app without the update issue, then you can add other customizations one after one in this app and perform the update. By doing this, it would
be easier to find out the root cause.
Anyway, you can take a look at the link below about updating app for more information:
