Error "Bad Request: invalid request" with large body request to qryn

[mk-raven]

When doing a big query request in loki api by all values in labels, there was error massage:

{"level":50,"time":1711468950014,"pid":19,"hostname":"qryn-read-545cb58978-k654s","name":"qryn","reqId":"req-2vj","err":"invalid request\nBad Request: invalid request\n at module.exports.transpile (/app/parser/transpiler.js:141:11)\n at scanFingerprints (/app/lib/db/clickhouse.js:248:29)\n at Object.handler (/app/lib/handlers/query_range.js:41:28)\n at process.processTicksAndRejections (node:internal/process/task_queues:95:5)","msg":"invalid request"}
In request about 3250 characters and starts by:
req":{"method":"GET","url":"/loki/api/v1/query_range?direction=backward&end=1711468949462000000&limit=3000 ...

Its could be problem with limits body size or something else..

Thanks for the report! Looks like any other invalid request so if you're positive it was not somehow truncated we should investigate. Since this was a query, could you show us the query causing this error or does it contain something fancy?

this happens on the log dashboard when the All variable is added.
the query looks like this

{k8s_cluster_name="cluster1", k8s_namespace_name=~"service1|service2|service3|service|service4|service5|service6|service7|service8|service9|service10|service11|service11|service12|service13|service14|service15|service15|service16|service17|service18|service19|service20|service21|service22|service23|service24service|service25|service26|service27|service28", level="WARN"} |= "" | json body="body"

If there are fewer services, the query works without errors.

@deathalt @mk-raven should be fixed in 3.2.18
