[jira] [Updated] (SOLR-11760) Accept Header is not honored / Errors
returned in XML instead of JSON
[ https://issues.apache.org/jira/browse/SOLR-11760?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Munendra S N updated SOLR-11760:
--------------------------------
Issue Type: New Feature (was: Bug)
> Accept Header is not honored / Errors returned in XML instead of JSON
> ---------------------------------------------------------------------
>
> Key: SOLR-11760
> URL: https://issues.apache.org/jira/browse/SOLR-11760
> Project: Solr
> Issue Type: New Feature
> Components: Response Writers
> Affects Versions: 6.6
> Reporter: Chantal Ackermann
> Priority: Minor
>
> We generally request JSON from SOLR, via HTTP with {{wt=json}} (without using a client impl).
> In case of fundamental errors, however, no JSON is returned but XML (either because {{wt=json}} is not transmitted correctly or the request handler that understands this parameter is not executed). It would be nice if in this case the `Accept:application/json` header could be honored.
