| We encountered this issue today when we upgraded to a new version of Blue Ocean (1.6.1 -> 1.9.0 ), along with a few dependant plugins. We found the following in logs: ``` SEVERE: Caught a IllegalStateException traversing the graph for run <project>/<branch>#9 Nov 14, 2018 3:49:43 PM io.jenkins.blueocean.commons.stapler.export.ExportInterceptor$1 getValue ``` Deleting the relevant build from Jenkins resolved the issue for us (in this case project <project>, branch <branch>, build 9 Blue Ocean now renders the tabs fine Worth checking your Jenkins master logs to see if this is the same issue for you! |
