[andre8888]

i have the same problem

[sahilchopra]

Fixed version
gem 'redis-browser', github: 'sahilchopra/redis-browser'

[andre8888]

@sahilchopra works great! Thanks for the fix!

[szajbus]

I'm hesistant to merge in the fix because it relies on Marshal.load which should not be used to load user-provided data.

@sahilchopra @andre8888
Can you please provide the value you hold in redis that is causing the problem? Maybe we can come up with a better fix for this issue that way.

[sahilchopra]

Hi Michal I am trying to access session from redis (set by devise gem). Let me know if you need any more information. Thanks S

+1 getting same error, can't view the value of key.

The value is HTML, we're using Redis as a page cache and have Rails taking care of the cache store.

Sidenote: The redis-browser prints the value as HTML, doesn't escape.

[Infusible]

I use redis v 4.0.8, but redis v 4.0.7 - OK.
