Import Building Block Extension Error


Import Building Block Extension Error



I am trying to import building blocks in my ThingWorx but can not successfully import getting 

another extension like mail extension imported successfully. anyone can help me?





Please share your application logs. Should be some dependency or build version compatibility issue while import

hi @TanmeyTWX 


in application logs, not any new log is displayed like an error or warning


in ss all logs was old log  

Need Application and error logs from Tomcat directory. You can find it in below path at your machine.

Program Files--Apache Tomcat -- Logs-- Application and error logs.


Please attach those logs file here.

hi @TanmeyTWX 


Thanks for your reply,


My Thingworx was installed in docker, so I copy these logs from a docker container 

Below are the last recent logs in the application log file

If you go through your logs you can observe the dependency import error. 

Entity Not Found : [PTC.DBConnection]  -this entity is required to make your import successful which is not there already.

I believe [PTC.DBConnection] is the database connection building block which is either not present in the composer or doesn't existing in your import file. You need to figure out this to resolve your issue.


Hope this helps:

Hi @TanmeyTWX 


In the building block extension zip file contains PTC.DBConnection Project/Entity available


and I have first import PTC.DBConnection and then try to import building block extension but getting same error 

Hi @ParthBhadiyadra.


Did you go through this section of the Help Center to make sure you are importing the base configuration first?
