An error is thrown

(node:17712) UnhandledPromiseRejectionWarning: TypeError: Cannot read property 'guild' of undefined
at Client. (C:\Users\kuchm\Desktop\DSTBOT\index.js:224:27)

( node:17712 ) UnhandledPromiseRejectionWarning: Unhandled promise rejection. This error originated either by throwing inside of an async function without a catch block, or by rejecting a promise which was not handled with .catch(). To terminate the node process on unhandled promise rejection, use the CLI flag `--unhandled-rejections=strict` (see https://nodejs.org/api/cli.html#cli_unhandled_reje... ). (rejection id: 1)

Here is the code:

client.on('messageReactionAdd', async (reaction, user,message) => {
      if (reaction.partial) {
 
        try {
          await reaction.fetch();
        } catch (error) {
          console.error('Something went wrong when fetching the message: ', error);
   
          return;
        }
      }
      console.log(`${reaction.message.author}'s message "${reaction.message.content}" gained a reaction!`);
      console.log(`${reaction.count} user(s) have given the same reaction to this message!`);
      var role1 = message.guild.roles.cache.find(role => role.id === "786640140440567849");
      guild.addRole(role1);
      
      if(reaction.message.content == 'Поставь реакцию  если не бот'){
        
        
 
    
    
      }
    });

The code where exactly the error is thrown

Answer 1

1 . the event messageReactionAddtakes only two parameters - messageReaction (the reaction object) and user (the user who put the reaction on the message) - the message parameter does not exist.
if you want to get the Message class, you should use reaction.message...
2. as I understand it, the error is in the value of the role1 variable - it is solved by adding reaction.before the message.
tip : use .get()to get something by ID, and .find()- to search by name / color, etc.
