Error duplicating data source

[Carlos_Afonso_Schmit]

Hello everyone. When trying to duplicate a data source, I’m receiving the following error:

I’ve cleared the browser cache, tried a different computer, and it didn’t solve the problem. What could be happening?

Hi everyone.

I’m letting you know that the problem has been resolved. I didn’t receive any notification from Google. I tested it now and it’s working normally again.

Thank you all for your help.

I am still experiencing this issue on my end.

Premise

• The owner of the data source is a@gmail.com.

• Anyone with the URL can view it (copying is also allowed).

Case 1 When copying with the owner’s account, the copy is successful without any issues.

Case 2 When using a non-owner account (b@gmail.com), the following error occurs:

Hi, I have the same problem, whether it’s on the a@gmail.com account or the b@gmail.com account

Hi, have you changed anything in particular? A link or something to make it work?

[Léo_Potlet]

Hi, did you find a solution ?

No, but someone found a workaround. See it here (I have not tested it by myself, but it should work): ERR_INVALID_RESPONSE error message when trying to copy dashboards I've created - #5 by Georges_BOURGUES . Not ideal but at least there is a way.

Hello.

I didn’t need to do anything here. It started working again automatically. I only use my own databases, not shared ones. I’m in Brazil, it might be a regional problem.

I ran the tests again and it’s working.

I am also experiencing this issue. When clicking on the copy datasource button (in google chrome) I am taken to a dead end URL:

Some more context regarding this issue:

• It only happens for 3^rd party connectors that have a template and the box to “Use template for new reports” box is checked

• The error is triggered because 3 parameters are mandatory to proceed; however, we do not know what those parameters are and when they became mandatory. We cannot find any documentation on how to populate those parameters.

Here are the 3 parameters:

• projectNumber

• workspaceId

• region

Our questions:

• How do we populate these parameters?

• When did they become required?

• Where is the documentation regarding populating these parameters?

Hello there,

I still have the issue on my side. Some of you resolved it ? Crazy that no one at Google is able to answer to us.

To add details that might help :

• I’m based in France
• I’m working on multiple datasources (Sheets, Big Query, Community Connectors, Native Google Connectors…)
• The issue started on 11th may 2026 as far as I know

Please Google, could you help us? @Arpna @Roderick @JenS @system @Rick_E @Michelle @Miqua

i’ve found the work around wanted to share with the community. on the report page go to manage added data sources and click “duplicate” in the row with the name of the source you want to copy. Al works

Hello, thank you for your reply. When do you think you’ll be able to get back to us? My situation is critical and I really need to be able to copy my data sources. Thanks

Hi there,

It has been over two weeks since this issue occurred, and it is causing a significant disruption to our business operations.

Since we currently cannot determine whether we should wait for Google’s resolution or start considering alternative solutions on our end, could you please at least provide us with an update on the current status?

Thank you for your help.

It seems the issue has been resolved!

Thank you!
