fauxton error

popojargo commented 6 years ago

I'm not having the error with the current master branch.

Should we allow blob: as script-src?

popojargo commented 6 years ago

@sergey-safarov What kind of attachment was that?

sergey-safarov commented 6 years ago

Hello Alexis (@popojargo) Database contains mp3 audio files.

Important Console contains same error when opened doc without attachments. I think attachment list is not generated because some of scripts failed.

techniccontroller commented 6 years ago

I am facing the same issue on my CouchDB installation. My version is 2.1.1 (installed from Source) and running on Raspbian Stretch. When I am clicking on "View attachments" nothing happens. My console in the chrome browser shows the same errors. I also tried it with the Edge and Firefox browser with the same result.

My attachments are .png and .jpg image files.

Antonio-Maranhao commented 6 years ago

The issue is fixed on master but it didn't make into the CouchDB 2.1.1 release. It was delivered a few days after the cut: https://github.com/apache/couchdb-fauxton/pull/999

sergey-safarov commented 6 years ago

Thank you @Antonio-Maranhao I closing this ticket

cluxter commented 6 years ago

Same issue here right now with the official Docker image couchdb:2.1.1.

popojargo commented 6 years ago

@cluxter As Antonio said, it was not released yet for 2.1.1 It not expected to be updated in the docker image

chegeiser commented 6 years ago

I've made the edits from #999 in my deployment to actions.js and to components.js but it I still have the problem of not being able to view the attachements (jpg) in Fauxton. I did notice that action.js line 217 deletes a few of items leaving the line as - I assume this should actually be - I've tried both ways and after restarting CouchDB neither way enables attachment viewing. Any ideas how to fix this, or why the problem remains? Thank you, Che

gdelfino commented 6 years ago

I am experiencing this issue to with Firefox. In the meanwhile I am using https://github.com/ermouth/couch-photon to be able to easily download attachments and for IE11 compatibility.
