Hello everyone,

I've opened CRM trace files and I saw the following error occur more than 900 times within an hours :

>Crm Exception: Message: The requested record matches a specified If-None-Match version., ErrorCode: -2147088246

>{"Error":{"InnerError":null,"Message":"CrmHttpException: The requested record matches a specified If-None-Match version."}}

Apparently, it occurs every time a user tries to perform an action in dynamics crm 365.

Our CRM version: Version 1612 (8.2.2.112) (DB 8.2.2.112) on-premises

Do anyone has an idea on what could be the problem?

It looks like an exception returned by internal error when an api call is done, it shouldn't happen if the header tag "IfNoneMatch" is null.

Maybe the browser/proxy is adding the header tag, or maybe you could force it to null when doing api calls..

public static HttpResponseMessage HandleGetMatchETags(CrmODataExecutionContext context, Entity entity)

{

if (CrmODataOptimisticConcurrencyHelper.CheckIfMatchAndIfNoneMatchAreNull(context))

{

return null;

}

CrmODataOptimisticConcurrencyHelper.ThrowIfIfMatchAndIfNoneMatchAreIncompatible(context, entity.LogicalName);

if (context.Headers.IfMatch != null && !context.Headers.IfMatch.Tag.Equals("*"))

{

string text = context.Headers.IfMatch.Tag.Replace("\"", "");

if (!text.Equals(entity.RowVersion))

{

throw new CrmHttpException(HttpStatusCode.PreconditionFailed, "The requested record doesn't match a specified If-Match version.", new object[0]);

}

}

if (context.Headers.IfNoneMatch != null)

{

if (context.Headers.IfNoneMatch.Tag.Equals("*") && context.Request.Method.Method.ToLower() == "get")

{

throw new CrmHttpException(HttpStatusCode.BadRequest, "The specified If-None-Match condition isn't valid for a GET request.", new object[0]);

}

string text2 = context.Headers.IfNoneMatch.Tag.Replace("\"", "");

if (text2.Equals(entity.RowVersion))

{

throw new CrmHttpException(HttpStatusCode.NotModified, "The requested record matches a specified If-None-Match version.", new object[0]);

}

}

return null;

}
