Deep Index Errors: 520, 502

Technical Issue Reporting
#17

if the IP would be banned, then you could not do any call in a specific time interval

anyway, send me the IP din DM

#18

I believe I’m experiencing this. I haven’t been able to make a call since this thread was posted.

#19

what error do you get?

#20

For the logs endpoint, I get unknown error or request aborted.

For erc20 metadata, sometimes empty response. Ex: https://deep-index.moralis.io/api/v2/erc20/metadata?chain=eth&addresses=0x8a6D4C8735371EBAF8874fBd518b56Edd66024eB

#21

this works for me now, I tried 10 times

#22

I switched my IP to a VPN provided IP and it works again. I have not triggered any rate limits yet. I suspect if I do, this same issue will happen to my new IP. So I will test that out after I finish building, or if im able to obtain another IP.

I increased my requests per second to 20, and now im facing the 502 errors again. This time, subsequent requests are met with a 504

#24

and if you decrease it now it works well?

we did a change in API backend recently (~15-30 minutes ago), if you see something strange it could also be because of that change

#25

correct, it works fine at 10 requests per second for small payloads.

Longer payloads now timeout with a 504 after a few minutes.

Its a bit disappointing though because the pro plan should be netting us about 60 requests per second if im not mistaken

#26

you have a request example for this?

#27

can you try now again with larger payloads?

#28
#29

i execute each of those 10 per second. It consistently fails with a 504

I was able to replicate that 504 error sometimes with that list

#31

now you should not get that 504 error

#32

The 520 error is back. It seems sending a high volume of requests triggers this. This time, the VPN trick did not work

#33

how frequently it happens? what type of requests you send? how many requests?

#34

Its sporadic. I hit /transaction/${txHash} anywhere from 100 to 1000 times depending on what i’m doing. After completely stopping use for about 30 minutes, i’m now again able to make requests.

#35

When that happens you are probably temporarily blocked.

What sort of timeframe are you running /transaction/ 100 to 1000 times? E.g. within 5-10 seconds. You may need to add delays in between requests.

This page lists endpoint weights but it doesn’t seem to list the weight for getTransaction or /transaction/. If it’s more than 1, this drastically reduces how many requests you make e.g. a weight of 1 is 60 requests per second, a weight of 2 is 30 requests per second.

#36

That would make sense. I have a rate limiter built into my request logic. At the moment it’s set to 55 requests per second. I see this error mainly during development so it could be the rate limits adding up rapidly between server restarts. I’ll reduce it and keep an eye on how often i send requests
