I was coding a Discord bot, and everything was fine. However, when I update discord.js from 13.8.0 to 13.8.1 and try to give members role by clicking button and submit a modal, it shows this error:

/app/node_modules/discord.js/src/rest/RequestHandler.js:350
  throw new DiscordAPIError(data, res.status, request);
        ^
DiscordAPIError: Missing Access

  code: 50001,
  httpStatus: 403,
  requestData: { json: undefined, files: [] }
}

I've checked the permissions of the bot, but it already had all permissions.

Code of the modalSubit:

const response = modal.getTextInputValue('verification-input');
if(response.toLowerCase()!=="lock"){
  await modal.reply({content:"Failed!",ephemeral: true});
  return;
}
modal.guild.roles.fetch('926252511201988678')
  .then(async role=>{
  await modal.member.roles.add(role);
})
await modal.reply({content:"Finished!",ephemeral: true});
 }
