My case too, is a single call, which occurs when the map is complete, therefore a single call, which transmits all the data at once. However, if you need your data to change the position, how can they not change? So either I didn’t understand your goal, or you’re using the wrong logic. I repeat, my case too is a single call, but an array contains several values together, therefore the values must be treated individually as a variable. Then, regarding the print string, if it first prints correctly and then prints 0, the error must be between the input received (which prints correctly) and the map update (which prints 0, therefore it doesn’t happen and empties?). It is likely that at some point the input is null, the map is overwritten once with the last value taken and gives in print string 0.
