Channel access denied

[MekkiNassreddine]

I have added a new organization to my consortium network. Successfully able to join the channels from the new organization peers. Now I m trying to get information about my channel using the following command :

peer channel getinfo -c my-channel

But I get this error as result :

Error: received bad response, status 500: access denied for [GetChainInfo][my-channel]: [Failed evaluating policy on signed data during check policy on channel [my-channel] with policy [/Channel/Application/Readers]: [implicit policy evaluation failed - 0 sub-policies were satisfied, but this policy requires 1 of the 'Readers' sub-policies to be satisfied]]

I get also in peer logs this error:
