Hi, I am using the below JSON Facet to retrieve the count of all the different collections in one query.
https://localhost:8983/solr/collection1/select?q=testing&shards=https://localhost:8983/solr/collection1,https://localhost:8983/solr/collection2,https://localhost:8983/solr/collection3,https://localhost:8983/solr/collection4,https://localhost:8983/solr/collection5,https://localhost:8983/solr/collection6&rows=0&json.facet={categories : {type : terms,field : content_type,limit : 100}} Previously, in Solr 7.6 and Solr 7.7, this query can work correctly and we are able to produce the correct output. { "responseHeader":{ "zkConnected":true, "status":0, "QTime":24}, "response":{"numFound":41200,"start":0,"maxScore":12.993215,"docs":[] }, "facets":{ "count":41200, "categories":{ "buckets":[{ "val":"collection1", "count":26213}, { "val":"collection2", "count":12075}, { "val":"collection3", "count":1947}, { "val":"collection4", "count":850}, { "val":"collection5", "count":111}, { "val":"collection6", "count":4}]}}} However, in the new Solr 8.0.0, this query can only work once. Subsequently, we will get the following error of 'require authentication': { "responseHeader":{ "zkConnected":true, "status":401, "QTime":11}, "error":{ "metadata":[ "error-class","org.apache.solr.client.solrj.impl.Http2SolrClient$RemoteSolrException", "root-error-class","org.apache.solr.client.solrj.impl.Http2SolrClient$RemoteSolrException"], "msg":"Error from server at null: Expected mime type application/octet-stream but got text/html. <html>\n<head>\n<meta http-equiv=\"Content-Type\" content=\"text/html;charset=utf-8\"/>\n<title>Error 401 require authentication</title>\n</head>\n<body><h2>HTTP ERROR 401</h2>\n<p>Problem accessing /solr/collection6/select. Reason:\n<pre> require authentication</pre></p>\n</body>\n</html>\n", "code":401}} This issue does not occur in Solr 7.6 and Solr 7.7, even though I have set up the same authentication for all the versions. What could be the issue that causes this? Regards, Edwin
