Your software
My Mautic version is: 5.0.2
My PHP version is: 8.0.30
My Database type and version is: 10.6.16-MariaDB-0ubuntu0.22.04.1

My problem is:
I cannot properly configure make.com with mautic, as make is not receiving fields which are needed to create/update a contact.
Checking the API endpoint contacts/list/fields, it is not returning any infos about the fields, only the ID itself.

Part of the response
{
“72”: {
“properties”: {}
},
“55”: {},
“54”: {},
“53”: {},
“52”: {
“properties”: {}
},

It has been working before. Unfortunately, I have no clue what have happened what could cause this problem.

Any help is appreciated.

This is the response from /api/users
I guess there is also something missing.

{
“total”: 2,
“users”: [
{},
{}
]
}
