upload document not working as part of Continuous integration bamboo - protractor

Question

I am trying to validate PDF document upload functionality however it is working fine in local where it picks the path from local folder however it is failing as part of Bamboo+Sauce+Qtest integration execution.
Below is the code snippet i have used to upload the documentin local which is working fine :
var path = require('path');
var absolutePath = path.resolve(__dirname, "../uploads/Replace.pdf");
element(by.css('input[type=file][ng-model="detailDocuments.selectedFiles.selectedIbl"]')).sendKeys(absolutePath);
browserActions.clickOn(applicants.uploadBtn('Replace'));
Below is the code snippet which i have used to upload document as part of CI.
var path = require('path');
var remote = require('selenium-webdriver/remote');
browser.setFileDetector(new remote.FileDetector());
var absolutePath = path.resolve(__dirname, "../uploads/Replace.pdf");
element(by.css('input[type=file][ng-model="detailDocuments.selectedFiles.selectedIbl"]')).sendKeys(absolutePath);
browser.sleep(2000);
browserActions.clickOn(applicants.uploadBtn('Replace'));
browser.sleep(3000);
In the bamboo it showing below error message:
