I have submitted the request to the Ideas Portal as suggested; however, I urge you not to treat this as a standard feature request or an enhancement, as it directly involves significant legal and security implications. In 2025, the ability to delete chat history is a core requirement for data sovereignty, especially for a tool designed for developers who often handle proprietary code and internal system architectures. Relying on users to simply avoid entering sensitive information is an insufficient defense when even the inadvertent exposure of an API key or an environment variable becomes a permanent, unfixable security vulnerability without a purge mechanism.

From a regulatory standpoint, the absence of a deletion feature places the platform in direct conflict with modern data protection laws. Under the GDPR Right to Erasure and the California Delete Act, users have an enforceable legal right to withdraw their information and have it permanently removed from a company's records upon request. Since AI chat logs in 2025 are increasingly subject to subpoenas in intellectual property and copyright litigation, denying users the ability to manage their history creates unnecessary legal exposure for both the developers and the organization hosting the assistant.

Thank you, I will use this. Have a great day

Thank you!!

This is what I needed (minus this line: Set tSC = $$$ERROR($$$GeneralError, tResponseQuickStream.Read()))

Interesting, I see this error: Illegal CSP Request : CSP Error  and here is the stack trace

Is there something I need to change in the web gateway?

Thanks

That space is being added by the error handler. There is no space between the last character and the tab delimeter in the input data. 

Enrico,

Thank you for your response  and for testing this in Ensemble. You can paste colorful Studio Code by selecting the text and clicking on the 4th from last icon which looks like a rectangle that has the greater and less than signs: <>. When you hove over it, it states "Highlight ObjectScript".

Thank you for your help . I ended up returning the list of child properties to the cube dimension, not the list of child ids.

Hi Evgeny

I was able to define a level that shows the list of kids ids for a given parent.%Id(). I used an expression tag and a %cube method .

But what is the syntax for displaying the data for the kids properties in the parents cube levels/properties. Sorry I could not see anything in the documentation.

 Thank you for your answer, Evgeny! The dads in this data set are conservative!  There are 500 dads with less than 5 kids each so the trick should work!.  

Goodness me, this works! Thank you

I did have to add the PublicList  attribute to both the calling and the invoked methods, otherwise it would not work!

Ex

ClassMethod Main() [PublicList =(var1, var2)]
{
    Do ..InvokedMethod()
    W !,var1
}
ClassMethod InvokedMethod() [PublicList =(var1, var2)]
{
    Set var1 = "ChangedInInvoked
}

Thanks for the debug answer.

Setting the credentials on the Operation did not work.

When I put a $$$HTRACE to write its value to UtilTrace, it is blank.

I had already tried that.

Previous comment recommended processing the file as a single message stream. That ended up slowing the message viewer so much for these large messages that that it is impossible to view the message at all  because the stream is too large .So this line by line approach is being explored.

What is your definition of a few k? Each line is about 25000 KB.
