-----------------------------------------
Summary: NotebookServer.java[onMessage]:377) - Can't handle
message com.google.gson.JsonParseException: cannot serialize
org.apache.zeppelin.display.Input; did you forget to register a subtype?
Key: ZEPPELIN-2628
URL: https://issues.apache.org/jira/browse/ZEPPELIN-2628
Project: Zeppelin
Issue Type: Bug
Components: zeppelin-server
Affects Versions: 0.8.0
Environment: Any
Reporter: Christian Fries
I have the following issue with imported notebooks: After import, clicking on
the notebook (opening it) will give a page with navbar and blank (grey)
notebook content. The log file show the following exceptions:
{code}
NotebookServer.java[onMessage]:377) - Can't handle message
com.google.gson.JsonParseException: cannot serialize
org.apache.zeppelin.display.Input; did you forget to register a subtype?
{code}
(stacktrace see below).
It is not possible to open the notebook. As a workaround you can go to "Jobs"
and run the notebook from there. After the notebook has run, it opens without
problems.
The error appears again if the notebook is exported to JSON and re-imported
again.
For testing:
- I have attached a notebook which JSON which shows the behaviour.
- The attached notebook requires net.finmath:finmath-lib:2.4.2. in the spark
interpreter and the Helium packages of ultimate-scatter-plot.
Stacktrace:
