When using the neuron search widget, I receive this error message, which does not disappear until I refresh the page. It also prevents me from selecting any neuron, with the same error

Occurs frequently, about every hour

Thanks for the bug report @ayesha-mrc! Does this still happen? And if so, does it happen only on specific search parameters, like annotations? And does this error appear as a result of initiating a search or some other operation?
