When try to access path map reports using Sitecore Path Analyzer, it shows following error in GUI

No data was found for the selected map in the selected date range. Please try selecting a different map or changing the date range.

And when checked in the log files, I can see following error

6492 00:07:15 ERROR [Sitecore Services]: HTTP GET URL http://hostname/sitecore/api/PathAnalyzer/tree?treeDefinitionId={68E713D8-A382-4378-8FB0-9D7F7AD14B25}&start=20180522T000000&end=20180722T000000&language=en&group={00000000-0000-0000-0000-000000000000}&filter=null

Strange thing is, when "Group Map Data" checkbox is selected (to group data by templates) reports showing without any errors.

Any help would be highly appreciated.

    Could you please post the complete stack trace? – Alex Shyba Jul 20 '18 at 17:28

1

It works for the grouped dataset because the node name is not attempted to be parsed as url and therefore the code path that blows up is not hit.

Try putting either "1" or "2" as value for the following setting in configuration: <!-- PATH ANALYZER - RESPONSE - NODE NAME RESOLVING MODE Possible values: 0(raw) | 1(name) | 2(displayname) Default value: 0 --> <setting name="PathAnalyzer.Response.NodeNameResolvingMode" value="1" />

This setting is defined in Sitecore.PathAnalyzer.Services.config so I would consider creating a config patch if this solution works.

0 means the node names will be resolved using "raw" mode and looks like some of the collected page urls in xDB have illegal chars, so the parsing blows up:

Exception System.ArgumentException: Illegal characters in path. at System.IO.Path.CheckInvalidPathChars(String path, Boolean checkAdditional)

As the comments suggest, 1 enables resolution by item name and 2 by display name (so it is more expensive).

My hunch is that you may be having wildcard items and therefore there is a chance that this won't help since they fall back to "raw" resolution by url.

So if this doesn't help, consider overriding Sitecore.PathAnalyzer.Services.Data.NodeFactory, Sitecore.PathAnalyzer.Services that is also defined in Sitecore.PathAnalyzer.Services.config, specifically this method: protected virtual string ResolveName(Sitecore.SequenceAnalyzer.Node node)

where you can put a breakpoint and find what value of node.Name causes the code to fail.

Hope this helps.

  • I have print the node path as you mention and it seems like paths contains some links/nodes pointing to css/font files which causes the error. Following is the node.name value before pathAnalyzer return the illegal character error "/css/fonts/ProductsNMarket.svg) format("svg""... is there a way we can filter out these illegal paths from reports ?? – scFootsteps Jul 26 '18 at 13:52
  • I have following brimit.com/blog/path-analyzer-custom-map-type-ajax-calls-filter to create a new filtered reports to remove /css from the paths as a test. After deploying the map definition, I still see that map disabled (ie. can't select that map from Path Analyzer). Is it takes some time till the map builds ? – scFootsteps Jul 26 '18 at 18:01
  • Okay. Now I can see the map as active in Path Analyzer. So it was disabled earlier until its been rebuilt. – scFootsteps Jul 26 '18 at 18:38
