We have found, with Confluence 6.15.1, that the Jira Issues Macro errors out if we put a Select List field in the list of output columns. The message it displays is misleading:
"Unable to render Jira issues macro. Connection to Jira has timed out."
But the error happens instantly, so there is no spinning until it hits a wait limit. If we remove the Select List field from the output columns then the macro renders successfully. We have replicated this with various different Select List fields, so it doesn't seem to be a problem with a specific Jira field.
Does anyone know why fields of type Select List might be a problem, or how to get around it?
