How to solve this error

[hien_nguyen]

3 days recently, my apps have a problem when I edit columns and save the preview app will be shown a strange error alert although the app still running app on the browser or App mobile normally.
{“Message”:"‘Request’ constructor failed: Error parsing Request parameter ‘perTableParams’ having value '{\r\n “BB Họp”: {\r\n “time”: “2021-12-11T07:09:56.945746Z”,\r\n “etag”: null\r\n },\r\n “_Per User Settings”: {\r\n “time”: “2021-12-11T07:09:56.945746Z”,\r\n “etag”: null\r\n },\r\n “Chi tiết họp”: {\r\n “time”: “2021-12-11T07:09:56.945746Z”,\r\n “etag”: null\r\n },\r\n “CTTP”: {\r\n “time”: “2021-12-11T07:09:56.945746Z”,\r\n “etag”: null\r\n },\r\n “Detail”: {\r\n “time”: “2021-12-11T07:09:57.1357466Z”,\r\n “etag”: null\r\n },\r\n “DSCT”: {\r\n “time”: “2021-12-11T07:09:57.1518316Z”,\r\n “etag”: null\r\n },\r\n “Data”: {\r\n “time”: “2021-12-11T07:09:57.1518316Z”,\r\n “etag”: null\r\n },\r\n “DSTV”: {\r\n “time”: “2021-12-11T07:09:57.3393379Z”,\r\n “etag”: null\r\n },\r\n “ThuChi”: {\r\n “time”: “2021-12-11T07:09:57.3393379Z”,\r\n “etag”:

Does anyone have the same problem?
And how can I handle it?

Just chiming in to say that I am getting the SAME error. So much for working on my apps on a Saturday morning when no one at work will bother me! The error goes away if I disable my Automation Bots, but that is pointless because I am trying to test the app sending email alerts. Thankfully it still works if I do the actual testing on a real mobile device since the error is only coming up in the web preview.

Edit: revert is pushed to Monday.

I’ve got the same problem. I’ve contacted Support and they are reverting the changes they made which triggered this error to happen.
The revert should happen today…

As you mention that is it connected to have automation bots activated. It’s interesting because I have random issues where the automation bots are not always fully working. Maybe both of those issues are interconnected.

I have been observing the same errors for the last few days, and even now.

Escalated.

We are aware of the problem. It is the result of a change I made several days ago but I only became aware that my change had this problem on Friday. I spent all day Friday investigating the problem. On Monday morning we will decide how best to fix it.

I am very sorry I introduced this regression.
My bad change was rolled back about 45 minutes ago.
Can you confirm that you are no longer seeing the “Error parsing Request parameter” error?

Sorry, I don’t get out to this community page too often. I’m sure you already know, but the Error parsing Request parameter is not happening anymore.
