Fetching user documents… Failed to parse JSON payload: TooDeep (ESP8266)
first I want to iterate to my users which document will match to my predefined parcelBoxNo., after that if it matched then it will go to orders, and retrieve the data/info of the orders trackingNo. and qrcodedata. I also want that in orders it will iterate again cause i need to integrate this to my keypad and qrcode scanner hardware and compare that data to the database data.’
