LinkedData component not robust to connectivity issues #61
Description
Describe the bug
If you are not connected to the internet, the linked data component will cause a NPE when attempting to read data from the web. This kills the app.
Affects
- Designer
- Blocks editor
- Companion
- Compiled apps
- Buildserver
- Debugging
- Other... (please describe)
Expected behavior
The component should gracefully handle lack of connectivity rather than causing an app crash.
Steps to reproduce
Create an app to read a TTL file from the web. Compile and install the app. Disconnect from the network. Run the app and attempt to load the file. Observe crash message.
