The physical root path of this SFS tree is longer than the configured max base path length 90. about unicorn

That's weird, because I just dealt with that same thing yesterday.

The Rainbow.SFS.SerializationFolderPathMaxLength is what you're looking for (I'll make that clearer in the error message). Check /sitecore/admin/showconfig.aspx to make sure that your config change is active.

Did you change it to 103 exactly or more than 103?

[thuatnguyen123]

I changed to 103 and more than but still error.
My web.config is active.

Thank for your feedbacks

Hi,

I just tried to replicate your configuration exactly with the same setup:

Unicorn configuration XML (overriding the base path to the one you provided):

<configuration name="Sample Configuration" description="This is an example of a description that you can attach to a configuration in Unicorn 3 to explain what it's for.">
    <targetDataStore type="Rainbow.Storage.SerializationFileSystemDataStore, Rainbow" physicalRootPath="D:\Projects\Sitecore\src\abcorp-site\abcorp.sitecore.abc\data\Unicorn\Default Configuration" useDataCache="false" singleInstance="true"/>
    <predicate type="Unicorn.Predicates.SerializationPresetPredicate, Unicorn" singleInstance="true">
        <include database="core" path="/sitecore/system/Field types"/>
    </predicate>
</configuration>

Rainbow.config:
<setting name="Rainbow.SFS.SerializationFolderPathMaxLength" value="90" />

This resulted in the error you received, as you'd expect:

So I altered my Rainbow.config:
<setting name="Rainbow.SFS.SerializationFolderPathMaxLength" value="103" />

It worked fine as soon as I did that, or values > 103:

If I look at it in /sitecore/admin/showconfig.aspx to see the merged config results, I see what's expected:

Are you using a build process where you deploy after a build to copy your configs? At this point I cannot reproduce your issue.

The steps I reduce the config :

• Change the value's SerializationFolderPathMaxLength 90 t0 190
  

• Clean then Rebuild Solution.

• Check my confign /showconfig.aspx. I saw that its normally and the values have changed.
  Other case I change the values' Web.config belong steps above.
  From : setting name="Serialization.SerializationFolderPathMaxLength" value="90" to value="190".
  Now I got the errors :

  Exception Details: System.InvalidOperationException: The MaxItemNameLengthBeforeTruncation setting (100) is too long given the SerializationFolderPathMaxLength. Reduce the max name length to at or below 10.

If the Rainbow.SFS.MaxItemNameLengthBeforeTruncation change the default value 100 to more than. The error as below :

Exception Details: System.InvalidOperationException: The physical root path of this SFS tree, D:\Projects\Sitecore\src\abcorp-site\abcorp.sitecore.abc\data\Unicorn\Default Configuration\Core Settings, is longer than the configured max base path length 103. If the tree contains any loopback paths, unexpected behavior may occur. You should increase the Serialization.SerializationFolderPathMaxLength setting to greater than 105 and perform a reserialization from a master content database.

Continues with SerializationFolderPathMaxLength's value equal 105 and more than.

Exception Details: System.InvalidOperationException: The MaxItemNameLengthBeforeTruncation setting (100) is too long given the SerializationFolderPathMaxLength. Reduce the max name length to at or below 10.

Do you have any idea for this ?

After I changed name "Default Configuration" to another name. Example : New Configuration. Same you above is Sample Configuration. I worked fine. I dont know why this.

Unicorn.Configs.Default.config :
configuration name="Default Configuration" description="Write something here about why this configuration exists and what it's for. Or remove the attribute; it's optional."

Thank you !
