Hi @Amaya2013,
This could be a case of a small typo. The error suggests that what you used in the Body is invalid json. Can you share the whole payload of the Body field?
Normally the payload should be something like the below. Can you make sure every line ends with a comma except the last one?
{
"AllowContentTypes": true,
"BaseTemplate": 100,
"ContentTypesEnabled": true,
"Description": "My Lunch List",
"Title": "Weekly Lunch"
}
Also double check that in the headers the word nometadata is one word, not with a space in it.
{
"Accept": "application/json;odata=nometadata",
"Content-Type": "application/json;odata=nometadata"
}
