Exception: Cannot read property 'BM_recycled' of undefined

[seanccc]

Hi, 

I notice some error log "Exception: Cannot read property 'BM_recycled' of undefined" in the runtime mashup log,  although it seems that the error doesn't affect my current page behavior , I'm afraid of the potential risk.  

The error doesn't tell me more reason about it ,  does anyone has clue on analyzing it ?

HI @seanccc    

1. What is the version of your Thingworx server?

2. Are you getting the error while creating a new mashup?

From the error, it looks like the mashup has some issues with binded Thing property and services. Please make sure the properties listed are defined, with specific types assigned to it. 

Thanks,

@vangne ,

I'm using Thingworx 8.4.2.   Just found that the error seems to be appear only when using session parameters.

@vangne ,

sorry, but what I found is not a solution , it's just a clue of reproducing the problem.

Hello Sean,

The error message suggests that you have an INFOTABLE session parameter  OperatorConfirmStartWorkOrderId. It has a string field BM_recycled, bound to the mashup parameter StartWorkOrderId. It seems that this session parameter is undefined, so you need to check where you are setting it.

@Constantine ,

Thank for you the analysis.  I do have a session parameter "OperatorConfirmStartWorkOrderId", but it's data type is string and I bind it to a mashup parameter "StartWorkOrderId"  .   I  don't know where the field BM_recycled comes from ,  the name seems to be a auto generated field ?  

Regards,

Sean
