SpamassRules should be a string for Message

[jooola]

While working with the https://api.mailjet.com/v3/REST/message endpoint, I faced the following issue:

Error decoding API response: json: cannot unmarshal string into Go struct field Message.Data.SpamassRules of type []resources.SpamAssassinRule

It seems like the SpamAssassinRule should either be a string or an array/object, but the client doesn't seem to be consistent with the API.

Since the API is the source of truth I prefer not proposing a PR.

Hey there, I'm facing the exact same issue calling the message endpoint. Is there any update ?

The API documentation states SpamassRules is a string :

https://dev.mailjet.com/email/reference/messages/#v3_get_message_message_ID

The source code states it's a slice of struct :

package resources 

type Message struct {
  ...
  SpamassRules       []SpamAssassinRule `json:",omitempty"`
  ...
}

A simple workaround before a fix is provided :

-       var resp []resources.Message
+       var resp []struct {
+               resources.Message
+               SpamassRules string `json:",omitempty"`
+       }
	err := mailjetClient.Get(&mailjet.Request{
		Resource: "message",
		ID:       id,
	}, &resp)
