Description

After adding fields with the Schema API the schema cannot be shown on the Admin UI anymore and reloading the Collection/Core throws an NullPointerException. The schema itself seems to work.

Steps to reproduce:

1. enable managed schema in example/solr/collection1/conf/solrconfig.xml

2. upload that config

sh example/cloud-scripts/zkcli.sh -z localhost:8575 -cmd upconfig -d example/solr/collection1/conf/ -n myconfig

3. create a new collection

curl "http://localhost:8983/solr/admin/collections?action=CREATE&name=mycollection&numShards=1&replicationFactor=1&collection.configName=myconfig"

4. add some fields

curl http://localhost:8983/solr/mycollection/schema/fields -X POST -H 'Content-type:application/json' --data-binary '[
{
  "name": "my_field",
  "type": "string",
  "stored": true,
  "indexed": true
},
{
  "name": "my_field2",
  "type": "string",
  "stored": true,
  "indexed": true
}
]'
