search services failed response from /api/v3/traces

[esnible]

Describe the bug

A V3 query fails and returns JSON describing an internal server error

{
  "error": {
    "grpcCode": 2,
    "httpCode": 500,
    "message": "search services failed: elastic: Error 400 (Bad Request): An HTTP line is larger than 4096 bytes. [type=too_long_frame_exception]",
    "httpStatus": "Internal Server Error"
  }
}

To Reproduce

I loaded JSON with test data, yesterday, using the Omnition load generator.

cd ~/src/synthetic-load-generator
gtimeout 5m java -jar ./target/SyntheticLoadGenerator-1.0-SNAPSHOT-jar-with-dependencies.jar --paramsFile ./topologies/

curl "http://localhost:16686/api/traces?service=frontend" succeeds without difficultly, returning about 100 traces.

A query that should be equivalent fails: curl "localhost:16686/api/v3/traces?query.service_name=frontend&query.start_time_min=2001-01-01T00:00:00-05:00&query.start_time_max=2022-12-31T23:59:59-05:00"

Expected behavior

• The /v3/traces query should return very similar info to /traces.
• Jaeger should log something when this happens

Version (please complete the following information):

• OS: Alpine Linux v3.13
• Jaeger version: Container image jaegertracing/jaeger-query:1.25.0
• Deployment: Kubernetes

What troubleshooting steps did you try?

I tried upgrading to the 1.28.0 image. Didn't help. Didn't try adding more logging yet.

If I try to use /api/v3/traces to get data more than 16 months the query fails with a 500.

In the example above, with a startTime of 2001 and and end time of 2022, the query asks for 8036 jaegerIndices. Testing with SPAN_STORAGE_TYPE=elasticsearch go run -tags ui ./cmd/all-in-one/main.go --log-level=DEBUG, I learned that the following a query for query.start_time_min=2022-07-15T00:00:00-05:00&query.start_time_max=2022-12-31T23:59:59-05:00 fails with an ES request for 171 indices but if I set start_time_min to 2022-07-15T00:00:00-05:00 it succeeds with 161 indices.

I considered trying to add something in validateQuery() but the exact number might vary depending on the index name.

That load generator is deprecated now, can you reopen when you reproduce with something like this? https://opentelemetry.io/docs/demo/services/load-generator/
