Summary

I have a graph with nodes from the ACDC module. If the module is not part of the setup and you open the project GTlab crahses.

Which software is probably the cause of the error?

The debugger indicates that there is an assert in the function Graph::restoreConnection(Connection* connection) which leads to the crash.
Of cause the assert it self is not the problem but the case of nodes which are not found.

The case of unknown nodes seems not to be considered in the function.

What is the current bug behavior?

A crash.

What is the expected correct behavior?

A warning that the connection could not be restored

Steps to reproduce

Build a graph with module specific nodes and then remove the module from your setup. Then open the project.

Relevant logs and/or screenshots

(Paste any relevant logs - use code blocks (```) to format console output, logs, and code, as it's very hard to read otherwise.)

GTlab environment

(Add details to your GTlab environment. If the bug relates to a module, please also add the module and its version.)

• Operating System+version:
• GTlab version:
• GTlab footprint: (Create und upload the footprint as XML via GTlab -> Help -> About GTlab -> Export Framework Footprint)
