Hello,

After reading a set of tags with system.tag.readBlocking, I would like to return their values.

I can return one tag value like this:  
`return {'json': {value':qualifiedValues[0].value`}}

Is there a way to return all tag values? Getting errors with this:  
`return {'json': {values':qualifiedValues.value`}

`return {'json': [qv.value for qv in qualifiedValues]}`

or if you’re dealing with something strict enough to not like top-level arrays,  
`return {'json': {"values": [qv.value for qv in qualifiedValues]}}`
