I set up a portal for arcgis and tried to publish a survey but I get the errorcode: 400. If I try to fix the error by deleting the folder in my portal the error code 500 (Internal server error) appears.
My survey is a simple test file without anything in it except the default "example-field".
Next thing is: I got a feature service on my portal and want to publish a survey based on it. When i try to use its design in survey123 i get an "feature service error". The same error occurs when I try to create a survey from any other example feature service listed.
Is there something in the settings of my feature service that might cause trouble with survey123? If so where do I fix it? I enabled the function "Feature Access" for the service in my Server Manager.
Thanks in advance!
