[SOLVED] Moralis streams filter

Moralis General
#1

Hi,
I’m trying to listen to token transfer on a ERC20 token. I’ve setted up a new stream service and I’m trying to add a filter allowing me to only listen to transfer towards a certain wallet. Here is the filter that I’m using

[
    {
      "topic0": "Transfer(address,address,uint256)",
      "filter": { "to": "WalletAddress"}
    }
  ]

I have this error :

Apparently something is wrong, I’ve tried tweaks for hours with no success. Can you see something wrong in my code ?

Thank you in advance

#2

this is the docs page for filters: https://docs.moralis.io/docs/filter-streams

you can try

eq: ['to', 'wallet']

Thank you
I would like to try it out but for some reason now, my webhook URL (that was working earlier) doesn’t work anymore.
Here is my webhook URL ( Using Moralis cloud function )

Here is the error I get :

I couldn’t find any specifications about webhooks on the doc, and I’ve tested my web hook ( Working properly when called from elsewhere ).

Any idea of what the issue could be ?

#4

That server doesn’t have a cloud function called myFunction.

#5

I know, I changed the function for my example
The function name is “processPayment”

#6

What is the actual Webhook URL you are using?

#7

The webhook has to receive POST requests and has to respond with status code 200

#8

Here is the webhook I’m using : https://vddeposst2fr.usemoralis.com:2053/server/functions/processPayment

It is POST request ready and it sends statut 200 when the right data is sent in the body

#9

can you test it with a CURL/postman request to see if it works as expected?

#10

I did, that’s how I tested out my cloud function.
It’s working perfectly fine there

#11

this is the error from the server for when I tried:

Nov 15 09:59:44Z vddeposst2fr.usemoralis.com moralis-server error: Failed running cloud function processPayment for user undefined with:

Nov 15 09:59:44Z vddeposst2fr.usemoralis.com moralis-server  error: Cannot read properties of undefined (reading 'to')
#12

Ok I figured out the issue, to be able to bond to my web hook, I need the first interaction to send a code 200, so I’ve just commented all my cloud function code to returned a text ( no operation on data ), just so Moralis streams could process it the first time and let me create my stream
Thank you for your help :pray:
