[yubing744]

Bug Report

Starcoin Framework version:

commit_id: 4ebe51bc86b82001f8ed04dadd51ffea47d73824 branch: main

Current behavior:

Create a proposal for adding members. If the incoming image_data is an empty string, it will cause the proposal to fail to add members after the proposal is voted successfully. Error: ERR_CANOT_EMPTY

Expected behavior:

After the proposal is voted successfully, members are added successfully.

Steps to reproduce:

  call 0x1::MemberProposalPlugin::create_proposal_entry
  params: [
          $daoType,
          'Apply add 0x76Ac08692318fd25E2E5e5c37662530B as member',
          '0x76Ac08692318fd25E2E5e5c37662530B',
          "",
          "ipfs://xxxxxx",
          100,
          0
  ]
