Composer-playground not working in firefox

Question

The composer playground web app doesn't work correctly in Firefox. It gives

Error: Object with ID 'undefined' in collection with ID 'chaincodes' does not exist

in Firefox, but it works perfectly in chrome. Any ideas?

Answer 1

I was having this problem which I solved by using the following commands

1. First stop the Fabrics and then composer by going to its development folder

   $cd fabric-dev-servers
   

   and then

   $ ./stopFabric.sh
   
   $ pkill composer-playground
   

2. Remove the .composer folder

   $ rm -rf ~/.composer
   

3. run the following command

   fabric-dev-servers/teardownFabric.sh

Afterwards re-run the ./startFabrics.sh and composer-playground commands, everything will work fine.

I've got the same problem locally, so the solution as suggested is to delete your cookies and browser storage. If you use this locally delete the cookies for localhost
