Error with Solr: Could not load conf for core

[maxpatiiuk]

I am trying to install Web Portal. These are the error I get when the solr is started (step 7):

Error message:

Also, here is the error message when trying to go through step 8:

[maxpatiiuk]

Installed everything from scratch on a new VM. Same issue again

[maxpatiiuk]

Still happens on a fresh VM Will test again with another exported .zip file

[maxpatiiuk]

Fixed after trying out a different .zip file

@maxpatiiuk what did you do different with your export? As we're running into this same issue when trying to use Solr 8

[maxpatiiuk]

Ups, my comment from 2020 is pretty vague, and I don't exactly recollect what resolved it. Possible solutions:

• Check if your query (export definition) includes the same field multiple times. Try using a different export definition, a simpler one, to see if that works
• The DataExport utility in Specify 6 has multiple buttons for initializing export - try exporting using one of the other buttons

I hardcoded it to stay with Solr 7.5.0 [image: image.png]
