attributes do not load when going to next page (DOMException) #831

flip111 commented 6 years ago

yesterday i installed portia with docker run -v ~/portia_projects:/app/data/projects:rw -p 9001:9001 scrapinghub/portia. When i click on New sample everything seems to work fine (although i can't figure out how to capture the underlying URL when i click on some text). Then when i leave sampling mode and go to page 2 the attributes are not extracted. When i back to page one they are also not extracted, but when i go into sampling mode again it works fine. In the console i see this exception
