Hello @kanglee_mbg,
Thanks for reaching out to us.
This error message is related to the ElasticSearch call we do when we try to get the active rules of a Quality Profile.
One way to figure out the Quality Profile that is the source of this issue is to disable some rules in the Quality Profile that your project uses. You can copy the existing Profile and deactivate randomly some/most rules. More information here.
After deactivating some rules, try to run the analysis again.
