Problem with transactions when sending messages from multiple clients

[Diden05]

We have several WhatsApp clients that use the same sqllite3 database (using PostgreSQL is not possible).
When sending multiple messages from multiple clients, there is a problem saving the session cache; I see this issue multiple times in the logs.

failed to save cached sessions: failed to store cached sessions: transaction: begin: SQL logic error: cannot start a transaction within a transaction (1)

Message sending function:

func WhatsAppSendText(ctx context.Context, jid string, rjid string, message string) (string, error) {
	if WhatsAppClient[jid] != nil {
		var err error
		// Make Sure WhatsApp Client is OK
		err = WhatsAppClientIsOK(jid)
		if err != nil {
			return "", err
		}
		// Make Sure rJID is Proper JID Type
		composeRJID := WhatsAppComposeJID(rjid)
		// Set Chat Presence to Composing
		WhatsAppComposeStatus(ctx, jid, composeRJID, true, false)
		// Compose WhatsApp Proto
		content := &waE2E.Message{
			Conversation: proto.String(message),
		}
		msgId := WhatsAppClient[jid].GenerateMessageID()
		SendRequestExtra := whatsmeow.SendRequestExtra{
			ID:   msgId,
			Peer: false,
		}
		// Send WhatsApp Message Proto
		_, err = WhatsAppClient[jid].SendMessage(ctx, composeRJID, content, SendRequestExtra)
		if err != nil {
			return "", err
		}
		// Set Chat Presence to Paused
		WhatsAppComposeStatus(ctx, jid, composeRJID, false, false)
		return msgId, nil
	}
	// Return Error WhatsApp Client is not Valid
	return "", errors.New("WhatsApp Client is not Valid")
}

How can this behavior be corrected?
