Finally found the solution:
Changed this:
myDb.deleteIssue(project, _id, (err, data) => {
if (err) {
return res.json({ error: ‘could not delete’, _id })
}
res.json({ result: “successfully deleted”, _id })
})
to this on if section:
myDb.deleteIssue(project, _id, (err, data) => {
if (!data || err) {
return res.json({ error: ‘could not delete’, _id })
}
res.json({ result: “successfully deleted”, _id })
})
