Using multi capabilities is throwing error - protractor

Question

I want to run my tests on multiple browsers and I am using the multi capabilities option to run my protractor tests in browser-stack.
Here is my protractor config file I am using
exports.config = {
specs: [
'./src/**/*.e2e-spec.ts'
],
commonCapabilities: {
browserstackUser: browserstackCredentials.user,
browserstackKey: browserstackCredentials.key,
'browserstack.debug': true,
'browserstack.local': true
},
multiCapabilities: [{
browserName: 'chrome',
os: 'Windows',
os_version: '10'
}, {
os: 'OS X',
os_version: 'High Sierra',
browserName: 'Safari'
}],
SELENIUM_PROMISE_MANAGER: false,
directConnect: false,
connectionRetryCount: 3,
connectionRetryTimeout: 90000,
framework: 'jasmine'
}
I get the below error when I run tests with these config. Below is the error I get :
[chrome #01-0] [13:46:12] E/local - Error code: 135
[chrome #01-0] [13:46:12] E/local - Error message: No update-config.json found. Run 'webdriver-manager update' to download binaries.

Appreciate your help.

Looking at the error, The problem is with the file update-config.json
The behavior of protractor is to first locate the update-config.json file which contains the information of chrome/firefox driver. If the same file is not located then Protractor throw the same error as you mentioned.
Fix - Go to the path node_modules\protractor\node_modules\webdriver-manager\bin which contains webdriver-manager file.
use >> node webdriver-manager update
This command will create selenium folder under the path " your project directory\node_modules\protractor\node_modules\webdriver-manager.
Once selenium folder is created then it will have version of chrome/gecko drivers and update-config.json file.
