Test object with id 'Object Repository/' does not exist.

[tigran.sargsyan]

Hello everyone.

Facing this problem: Katalon test suites pass correctly in Katalon Studio on Windows 10, but some tests from the same test suites fail on Linux.

Here is a part from log:

Full marks for posting your errors completely.

Zero marks for not showing your code and other pertinent material.

All your errors surround the “verify” APIs. Did you try “wait” APIs?

[Russ_Thomas]

Much better info, thank you.

Now try the wait APIs but give them adequate time to “wait”. For example:

// Step 1. Verify 2.
WebUI.waitForElementPresent(findTestObject(‘Object Repository/App/HomePage/div_Path’), 10)

Setting them to zero is not helping you.

[tigran.sargsyan]

Thank you, but this also threw the same error.
P.S. Same error when I try to setText, sendKeys, etc. The problem is not with all elements in Object Repository, but with couple of them.

[Brandon_Hein]

I have a few questions that may point to the cause of your issue:

1.) Are you using the most current version of the studio (current version is 5.10.1)?

2.) This doesn’t usually make any functional difference, but when you’re specifying the path to any object in the repository, you can omit the ‘Object Repository/’ portion of the path, as the ‘findTestObject’ family of methods already knows to look in the Object Repository. So instead of:

findTestObject(‘Object Repository/App/HomePage/input_searchBox’)

try:

findTestObject(‘App/HomePage/input_searchBox’)

3.) I noticed from the screenshot of the repository that you’ve provided that the input_searchBox object in question has a different icon in the explorer: than a usual Test Object: . I’m not sure it makes any difference, but since you mentioned that only SOME of your objects have this problem, it may be worth investigating. At the very least, I would delete the Test Object and recreate it, then try again.

[Brandon_Hein]

@Russ_Thomas

Setting them to zero is not helping you.

This goes back to my topic from a while ago: Allow for timeout of 0 seconds for WebUI.verifyElement_____ calls. I’m assuming that OP wants to validate the existence of elements immediately, hence the ‘0’ argument in their original verifyElementPresent() approach.

[tigran.sargsyan]

Thanks for your response @Brandon_Hein.
1.) I am always updating Katalon, so its the most current version.
2.) Removing “Object Repository” part leads to same error, written bellow.
3.) Thanks for notice. When I try to open that element in Katalon GUI on Ubuntu it doesn’t even open. I’ll try to delete/recreate and will let you know if that help.

The thing that’s foxing us is that it fails on Ubuntu but works fine on Win10. Strange.

@tigran.sargsyan

3.) Thanks for notice. When I try to open that element in Katalon GUI on Ubuntu it doesn’t even open. I’ll try to delete/recreate and will let you know if that help.

Gotta be related to this! I imagine it’s why you’re getting a null for that object.

[duyluong]

Hi @tgran.sargsyan

Thanks for your provided information. The problem can occur when:

1. The object doesn’t exist
2. Katalon Studio could not read the object’s information.
   We think it should be the second one. Please set read and write permission to your project folder by using this command:

chmod -R 755 <your_project_folder_path>

And restart Katalon again.

[tigran.sargsyan]

Thank you all for responses.
Hi @duyluong. Thanks for response. As @Russ_Thomas mentioned, the strange thing is that the same test suite passes on Windows (so I think this objects exist), part of it passes on Ubuntu (so I think that project folder has read/write permissions). Only 2-3 elements cause failings. This also happens on other projects and again only few elements cause failings on Ubuntu (same test cases always pass on Windows).

[Brandon_Hein]

Have you tried rebuilding that Test Object from scratch? Obviously Ubuntu can open some of your other objects, so it’s got to be something wrong with that particular one (and others maybe).

[tigran.sargsyan]

Deleting/recreating these test objects fixed failing test cases. Thank you very much for your responses, Russ_Thomas, Brandon_Hein and duyluong.

[Brandon_Hein]

Good to hear! Please consider marking a response as the solution to this problem, so others can quickly find the fix.

Also as an FYI, passing a ‘0’ for the timeout argument in:

WebUI.verifyElementPresent(findTestObject(‘App/HomePage/input_searchBox’), 0)

isn’t going to do what you might expect. Refer to my topic on this from a while back:

Allow for timeout of 0 seconds for WebUI.verifyElement_____ calls

The user should have the option to validate that an element exists/is visible/etc in the DOM immediately. This is currently not possible with the standard WebUI.verifyElement____ methods, as providing a timeout of ‘0’ seems to default back to the 30 second timeout, and often the next best option (waiting 1 second) is not viable. Take for example the following scenario, which should demonstrate that waiting 1 second is not a good alternative: We would like to test a form that contains many, man…
