Internal Server Error 500 when trying to set up external Solr

[trist...@gmail.com]

Hello,

I'm helping an organization I work for move to ArchivesSpace with external Solr. I've installed AS and Solr on the same server and Solr is running and the schema seems to loaded correctly into the core named "archivesspace". I can see it's active by going to port 8983 in my browser. I've loaded the data into the database and run the setup script, which was successful. However, when I start AS with the ./archivesspace.sh method, I get an Internal Server 500 error. I've checked the config and the AWS security settings, so am a bit stumped. Thanks in advance for any help! Error copied below

Hi - it looks like there is a problem with your Solr server. You can validate that the server and core are in order prior to running ArchivesSpace using something like curl:

curl "http://localhost:8983/solr/archivesspace/admin/file"
{
  "responseHeader":{
    "status":0,
    "QTime":37},
  "files":{
    "Dockerfile":{
      "size":559,
      "modified":"2022-03-09T22:35:38.019Z"},
    "delete.sh":{
      "size":330,
      "modified":"2022-03-09T22:35:38.019Z"},
    "lib":{
      "directory":true,
      "modified":"2022-02-03T03:24:56.115Z"},
    "schema.xml":{
      "size":18400,
      "modified":"2022-03-29T23:40:37.428Z"},
    "synonyms.txt":{
      "size":0,
      "modified":"2022-03-09T22:35:38.019Z"},
    "solrconfig.xml":{
      "size":3046,
      "modified":"2022-03-10T18:19:31.096Z"},
    "stopwords.txt":{
      "size":0,
      "modified":"2022-03-09T22:35:38.019Z"}}}

You can follow the instructions for installing Solr 8.x here:

https://solr.apache.org/guide/8_10/installing-solr.html

Once your server is running, create a core using the files in your ArchivesSpace distribution:

cd /path/to/your/archivesspace

solr create_core -c arhivesspace -d solr -p 8983
