I am getting the following error and unable to understand the reason for its occurrence. I tried to find solutions on Google but different people are facing this issue for entirely different applications.

Node Version: 17.0.0

The code execute perfectly till ok tcp

Error:

I have traced the error to zklibtco.js The error occurs in following function when returning the data.

async getInfo() {
    try {
      const data = await this.executeCmd(COMMANDS.CMD_GET_FREE_SIZES, "");

      return {
        userCounts: data.readUIntLE(24, 4),
        logCounts: data.readUIntLE(40, 4),
        logCapacity: data.readUIntLE(72, 4),
      };
    } catch (err) {
      console.log("noway");
      return Promise.reject(err);
    }
  }

I have changed it to this and it is now working fine:

async getInfo() {
    try {
      const data = await this.executeCmd(COMMANDS.CMD_GET_FREE_SIZES, "");

      return {
        userCounts: data.readUIntLE(0, 4),
        logCounts: data.readUIntLE(0, 4),
        logCapacity: data.readUIntLE(0, 4),
      };
    } catch (err) {
      console.log("noway");
      return Promise.reject(err);
    }
  }
