SerializeJSON and DeserializeJSON not working properly for cfcatch block

I have a requirement for storing all the ColdFusion exception details in a database table. So I am planning to serialize the cfcatch structure and store it in db, but I have an issue.The structure before and after the serialization is not the same. So for testing purpose, here is small snippet of code I tried on my local,

<cftry>
 <cfset a = 5/0>
 <cfcatch type="any">
     <cfdump var="#cfcatch#">
     <cfset a = SerializeJSON(cfcatch)>
     <cfdump var = "#DeserializeJSON(a)#">
 </cfcatch>
</cftry>

Here is the screenshot from the first dump (Original cfcatch). enter image description here Here is the screenshot from the second dump(i.e serialize and then deserialize)

Solution

  • Entered as a comment on the OP question, but adding here as well in case it's useful to others.

    Try:

     <cfset a = SerializeJSON(duplicate(cfcatch))>

    Although when you dump it, the cfcatch data looks like a ColdFusion struct it isn't really, the duplicate forces it to a ColdFusion struct which it can then serialize. Be aware that duplicate does a deep copy.
