Sharepoint 2013 Search Crawl Error

Zunaid Valley 1 Reputation point


Our Sharepont 2013 Server gives an error with one of the content sources when the crawl completes.


The SharePoint item being crawled returned an error when requesting data from the web service. ( Error from SharePoint site: *** Client found response content type of '', but expected 'text/xml'. The request failed with the error message: -- Value cannot be null. --., CorrelationID: 8c83ab9f-f530-a002-4db5-c8e2034a8ba5; SearchID = 9F295759-169A-4D88-ACF4-0B1400246B37 )


Any help resolving this issue would be helpful
Thank You and stay safe.
Kind Regards

    Please check as following:

    1. Has this content source been crawled before? Double check if you are using the correct URL for the issued content source.
    2. Do crawls for others content sources finish without error? Is there anything special or worth mentioning about this issued one? Check the Event Viewer or ULS logs while crawling for other potential error message on related issue.
    3. Do an Index Reset via Search Service Application if necessary. After that, run a full crawl again.

    See another post with similar issue here: “The SharePoint item being crawled returned an error when requesting data from the web service. ( Error from SharePoint site: Value does not fall within the expected range. )”.

    A few more things to check:

    1. Make sure you use only default zone URLs in the Content Sources (also this issued one). In this scenario, the URL for the issued content source should be also HTTPS.
      Reference: Beware crawling the non-Default zone for a SharePoint 2013 Web Application.
    2. Make sure you have full access to the content source URL.
    3. Disable the Loopback check on your local servers.

    One more reference that might help: SharePoint crawling not working with non-default zone (public facing site).
