> As reported by Li Cao on the mailing list:
> {quote}I am using solr 8.3.0 in cloud mode. I have collection level
> autoscaling policy and the collection name is “entity”. But when I run
> autoscaling simulation all the steps failed with this message:
> "error":{
> "exception":"java.io.IOException:
> java.util.concurrent.ExecutionException:
> org.apache.solr.common.SolrException: org.apache.solr.common.SolrException:
> Could not find collection : entity/shards",
> "suggestion":{
> "type":"repair",
> "operation":{
> "method":"POST",
> "path":"/c/entity/shards",
> "command":{"add-replica":{
> "shard":"shard2",
> "node":"my_node:8983_solr",
> "type":"TLOG"}}}},
> "replicaInfo":null}}},{quote}
> The simulation package internally uses v1 APIs but the requests created by
> the autoscaling framework may use v2 APIs. The utility class {{SimUtils}}
> converts v2 request parameters to v1 parameters, without actually using the
> apispec or v2 Api handlers (as that would mean adding more complexity to the
> simulator, and only tangentially related to the autoscaling).
> There's a bug in this utility when converting the path of the request - V2
> apispec uses {{/c/\{collection}/shards}} when manipulating shards and
> replicas - unlike V1 which uniformly uses {{/collections}}. The utility class
> doesn't account for this path difference and creates invalid collection names.
