Still confuse Could you help me ?

#6

when you go to https://admin.moralis.io/web3Api you should find a new API key that you can try to use to see if it works now

#7

i have tried new api key also and didnt work. I just have 60 -120 request/ minute but still error

#8

what kind of requests are you making, do you have any specific error message? for 503 error, it can happen sometimes and all you have to do is to retry same request

#9

You can see my code 2 execute 2 kind of requests. I dont know why some request they return 503. And after 250 request. The response time is really slow

#10

I am not able to easily understand that code? what does it do? does it use pagination?

#11

i am looping 500 times to get 500 wallet address information. I also set 1 second delay time for each request. But i dont know why it’s errors. Moralis didn’t support multi address 1 time. Just one by one

#12

503 error could happen from time to time, that should not be caused by your code (and when it happens you should retry same request again), I don’t know about 500 error

you can see here how to format code on forum: READ BEFORE POSTING - How to post code in the forum

can you log every request that you make to see how many requests you make and if you really make them with delay?

#13

I dont know but some request have 503 error. Retry is not good solution. But i didn’t request many time but. some is still 503. It’s not clear.

#14

did you try again multiple times?

did you try with retry in case of 503 errors and it didn’t work?

#15

How about if it will fail again. I use javascript to try catch but just 1 times. If it fail again how can i process.I want to all request 100% successfully at least give me a reason to fail

#16

We have 503 sometimes on BSC because of the load and until we scale our systems it may happen

You can retry the request if it happens

It’s not your fault so there is no reason we can give you

If you need 100% successful calls - come back in a few months when we solved the BSC scaling project we have now

EDIT - we may actually have a solution for this BSC issue already this week
