Description

Describe the Bug

When calling the et_feeder_node->comm_size() method of ETFeederNode, it is found that the read comm size is 0, but the expected result should not be 0.

After investigation, the acquisition failed because the type obtained in src/feeder/et_feeder_node.cpp:28 was attr.int64_val() instead of attr.uint64_val(). it causes the method to return a result of 0

// in src/feeder/et_feeder_node.cpp:28
ETFeederNode::ETFeederNode(std::shared_ptr<ChakraProtoMsg::Node> node) {
...
    } else if (attr_name == "comm_size") {
      this->comm_size_ = attr.int64_val(); // attr.uint64_val() method should be used here
...
}

Looking forward to fixing this bug and checking if there are similar issues elsewhere.

Research direction

Start in src/feeder/et_feeder_node.cpp:28 and inspect how comm_size is read from the node attributes. Verify the unsigned value path and search the feeder code for similar integer-type mismatches. Done means comm_size is no longer read as zero for valid unsigned values and related checks pass.
