I have a strange issue with API created field.
I use API call to create a checkbox field
"label": "Opt-In Consent",
"validationMessage": "This field is required.",
After the field is created - there is no input on the field. If I remove this field are recreate it through UI editor in the Design studio with the same parameters - everything works fine. See the second checkbox field.
Does anyone have the same problems? All other fields are working fine
In the editor, they both looks the same
I know this was an old issue, but it is still occurring today. I was able to "fix" this through the UI by changing the field type from Checkbox to Select and back again. Once I saved after that, the input was there. I'm going to create a case with Marketo support to get this bug fixed.
