An error occurred on the server. Server Response: Incidents failed: Bad Gateway (502)

My app is throwing the above error when I go to re-submit a form which has been edited. 

 

A New Form submit works fine, but when I go back to the gallery, select any previous record, and try to edit it does not submit.

I've tried good ol' google with no luck, some people seem to suggest the error should go after a few tries, but no luck there either. I've tried refreshing the data source etc. and I've also remade the app from scratch and it throws the same error again.

 

The main error message appears to be:

"message": "Error reading string. Unexpected token: StartObject. Path 'Value', line 2, position 13.\r\nclientRequestId: 5e78521b-d14b-433f-a888-5edb7abfba9c\r\nserviceRequestId: 5e78521b-d14b-433f-a888-5edb7abfba9c"

 

Is this referring to a specific data card? Can I identify where 'line 2, position 13' is?

 

I did the full monitoring troubleshoot and it came up with the attached details. 

 

Any help is greatly appreciated, this is the last hurdle on a project which has taken me quite some time!

UPDATE: I found a fix and thought it would be prudent to provide it here for others who come across a similar error:

 

1) I duplicated the screen and deleted each data card one by one until I found the one which was creating the error (turns out it was a dropdown which is linked to a Choices sharepoint list)

2) I found out that the error did not occur if I 'edited' this data card before re-submitting (even if I just deleted and selected the same option)

3) Logic showed this was probably due to my DefaultSelectedItems property which was:

If(
   ReportForm.Mode = FormMode.New && DataCardValue2.Selected.Value = "Fire Report", ["Fire incident"],
     ReportForm.Mode = FormMode.New && DataCardValue2.Selected.Value = "Building Report", ["Damage to property"],
      ReportForm.Mode = FormMode.New && DataCardValue2.Selected.Value = "Incident Report", ["Miscellaneous"],
      ReportForm.Mode = FormMode.Edit, [Parent.Default])

 

To fix, all I had to do was change [Parent.Default] to ThisItem.'Incident Category'.

Thank you !! 4 days i battled with this error. Same case, a dropdown which is linked to a Choices sharepoint list with DefaultSelectedItems property.

I just deleted it, added it again, modified properties as before and it works...

I was getting a similar error, lots of googling to try and isolate the problem and this was it. I was generating collections on a toggle to update default selected items in a choice box, and this saved me hours of searching. Thank you!

I have just come across the situation.

If this returns Bad Gateway with error code 502, do the following. 

 

Remove the "i:0#.f.|membership|" prefix in the "Claims" tag and pass the email in the claims directly.

 

Example:

{.. Claims: "i:0#.f.|membership|"&Lower(User().Email) } --> this is a normal syntax.

 

Try this, 

{.. Claims: Lower(User().Email) --> This may work for you.

 

Happy Coding!!!
