The second scenario failed due to:
2020-06-19 12:45:35.053 UTC [policies] SignatureSetToValidIdentities -> WARN 0ef signature for identity 0 is invalid: The signature is invalid

How many peers are endorsing? Are you always getting endorsement from the same exact peers?
What is the endorsement policy for both the chaincode and the collection?
Can you provide the uninterrupted log?

@email4tong : I tried deploying the chaincode with this policy, it gave me an Error: invalid collection configuration: invalid endorsement policy. 

Thanks.

    Curious about this policy,

    "endorsementPolicy": { "signaturePolicy": "OR('Org1MSP.member'), OR('Org2MSP.member')" }


    was it accepted as a valid policy? if it was accepted, should this be a bug? what does this policy exactly mean? Is it the same as this

    "endorsementPolicy": {
          "signaturePolicy": "OR('Org1MSP.member', 'Org2MSP.member')"
        }

    Thanks.

    The endorsement policy check only checks which peers have endorsed, not which clients have submitted the transaction. The peer validation logic is deterministic in this regard.
    Could you share the Org1 peer log showing it working once, and not working once, with no other changes inbetween? Please highlight the log timestamp of endorsement and validation in both cases.


    Thanks,

    I ran the network again, to double check. The inconsistency issue still exists. The issue occurs even when I pass OR("Org1MSP.Member") as the EP and try to update the key via Org1 client (which is an authorized peer).

    the above error seems to match your old definition --     "endorsementPolicy": { "signaturePolicy": "OR('Org1MSP.member'), OR('Org2MSP.member')" }

    Anyway, I do not have expertise in this. If Yacov looks at this message, he might clarify    .

Sorry for typing it wrong. The endorsement policy in my collections config is as follows:

"endorsementPolicy": {

    }

Setting memberOnlyWrite to false is deliberate because I want the peers of only Org2 and Org1 to be able to write to the private data collection; and not any other Org that might join the network in future.
