Gateway event script 2

Also, I believe system.tag.writeBlocking requires lists even for singular values so it should be system.tag.writeBlock(['myTag'], ['true'])

Actually, depending on the version, single elements passed as strings will work.

Attribute Error in Component Custom Method

Fairly recently we made a sneaky change to the read and write functions to allow single elements to be passed, since it’s a common ‘papercut’ issue for new users and our training department. The preferred syntax is still to call it with a list, but single values are accepted - that explains the syntax in the OP working. Basically correct - gateway event scripts are the only system that still uses ‘legacy’ scripting, and therefore needs you to reimport system inside any defined functions.
