The tag tagname in container containername is empty.
A tag has been included in the config.txt file which requires a value, but no value has been provided.
for example, a traincar asset that included scripting has these lines in the config.txt file:
kind "traincar" trainz-build 3.5 engine 0 enginespec <kuid:-1:42004201> script class "reefer"
The error message was:
- VE26: The tag 'script' in container 'traincar' is empty.
If the tag is not required it can be deleted. If the tag is required then a valid value for the tag must be provided. In this case the correct value is the script name "reefer".
