I suspect fetch is having problem due to this commit: https://github.com/apache/lucene-solr/commit/cb9f151db4b5ad5c5f581b6b8cf2e5916ddb0f35#diff-98abfc8855d347035205c6f3afc2cde3
Later local params were turned off for anything but the lucene qparser. Which means this query doesn't work if /select is using edismax etc... This needs to be fixed. Can you check to see if the qparser is for the /select handler on your install? Anyway fetch needs to be reverted back to it's previous implementation before the above commit basically broke it.
