If you upload your .dink file (including advanced HTML scripts) on admin.dink.eu and you receive an error RequestTooLargeError('The request to API call datastore_v3.Put() was too large.',) on your publication, that might mean that the scripts you included are too large to be written to the datastore. The total size of the code for 1 slide can be a maximum of 1MB. If that size is exceeded, it will result in an error.
The problem can be avoided by cleaning up your code, or by using minification. You can read more about minifying resources here.
