Invalid cannot index property of type text into type NSARequest

Question

Please help solve the below error. I have renamed a column name in CDT and DataStore published to DB. This broke the process model and keeps throwing this error. The Write to DB node is writing to DB successfully, but throws this error instead of continuing to next node in process model. 
 I have verified Record Type functions and interface and couldn't find anything much. Please advice where could be the issue.

Try to remap the cdt datatype in the process variables. Then also remap the cdt datatype in the activity class variable. It seems to be the latest change was not reflected in either of the variables.

Hi, 
1.Ideally, it appears the related CDT might not be updated. Hope impact analysis is done or may be you can remap the CDT at the reference artifact where is being used. 
2. Sometimes, using dot throws an error while the value is NULL. I would suggest to use index() to overcome the same. 
3. Is your CDT is multiple ? If so use cast in apply() function. 
 
Thanks.
