Hi, ive got this server action.
the await fetch never seems to execute.
The console log before the try works, but then its dead. No request reaches my backend, no further console.log will be printed.
The action returns a generic error:

0:["$@1",["development",null]]
1:{"message":"Error","response":{}}

My Code:

interface State {
    message?: string,
    path?: string,
}

export async function ClanTagAction(prevState: State, formData: FormData) {
    const sessionToken = cookies().get('next-auth.session-token')?.value
    if (!sessionToken || sessionToken.length === 0) return prevState;

    console.log("THIS PRINTS");
    try {
        const clanTag = formData.get("clanTag");
        const response = await fetch(ENDPOINT_CHANGE_CLANTAG, {
            method: 'POST',
            headers: getDefaultHeader(sessionToken),
            body: JSON.stringify({clanTag: clanTag}),
        });
        const result = await response.json();
        console.error("result", result);
        revalidatePath(prevState.path ?? "/");
        return {
            message: `Success`,
            response: result,
        };
    } catch (e) {
        return {
            message: "Error",
      };
    }
}
