Fiware-quantumleap 在获取和更改更新值时遇到问题

Question

The values sent to the Fiware IoT-agent-json are being successfully updated in CB. But, quantumleap 0.7.6 won't get them anymore (It was working just fine and cratedb was storing the recieved data normally)..the sanity check shows that It's healthy..I think something is going wrong with the DB. The logs shows something like this..

Does anyone have an idea what's the problem here? Thank you!

Answer 1

The error is clearly an attribute name as reported by the message: InvalidColumnNameException: "5.9" contains a dot

Try using 5_9 as attribute name.
