Exception: Unknown Selector operator: ''

<b>Fatal error</b>:  Exception: Unknown Selector operator: '' -- was your selector value properly escaped? field='id', value='!=9022', selector: 'template=city,sort=random,start=0,id!=9022,id!=9011,id!=9028,id!=1099,limit=8' (in /opt/bitnami/apps/processwire/htdocs/wire/core/Selectors.php line 357)

I'm getting this confusing error with a selector, it seems to be implying that id isn't a field which is obviously not right. Any idea what might cause this bug?

That's strange. Which PW version are you running? Could you try moving the sort=random and start=0 to the end of the selector string and see if the error still comes up?

i've reduced it to the simplest selector and still the same error. My version is 3.0.42.

The following work

template=city,id=9022,id=9011,id=9028,id=1099

template=city,id!=9022

so it seems the issue is with having multiple does not equal clauses.

i'm an idiot, having spaces apparently breaks the selector.
