400 Bad Request when using NextToken on listFinancialEventsByOrderId

[fernlop]

I'm trying to get the next page of financial events on the listFinancialEventsByOrderId (path: /finances/v0/orders/{orderId}/financialEvents ) method, but I receive a bad request error.

What i try:

GET Request on: https://sellingpartnerapi-eu.amazon.com/finances/v0/financialEventGroups/{MyEventGroupId}/financialEvents?NextToken={NextToken}

Response: Data is empty, Code 400, Bad Request

When i try with a Token that is invalid (ANY String) i receive the following:

StatusCode: 200
data: { payload: {} }

Only with the correct NextToken i get the Bad Request error.

This results in 2 problems:

• Can't get next page with NextToken
• No error message when using an invalid token, instead return empty payload

Can someone access the listFinancialEventsByOrderId with NextToken successfully? I would appreciate the feedback.

Hey @fernlop i didn't try that, but it seems similar to issue amzn/selling-partner-api-models#1148 It basically says that NextToken should be sent as header. Can you try that?

[fernlop]

@stefnats No doesn't work, if I put the NextToken only in the header it continues to give me the first page of results.

[fernlop]

UPDATE: NextToken doesn't work with listFinancialEvents eighter.

ALSO INTERESTING: When using the getOrders method, I can use the NextToken in the QueryParams and it works. Other users like in amzn/selling-partner-api-models#1148 can't use it. I'm on the EU servers, maybe there is some difference? For me it works with NextToken in the QueryParams but not in the header.. /orders/v0/orders/?CreatedAfter=2021-02-01T00:00:00.000Z&CreatedBefore=2021-02-28T00:00:00.000Z&MarketplaceIds=A13V1IB3VIYZZH,A1805IZSGTT6HS,A1F83G8C2ARO7P,A1PA6795UKMFR9,A1RKKUPIHCS9HS,A2NODRKZP88ZB9,APJ6JRA9NG5V4&NextToken=2iqSofqEJZCaJqJYLDm0ZAmQazDrhw3CgJalwszeU.................

[stefnats]

Hm that's interesting. Just out of curiosity, which library are you using for making that call?

[fernlop]

@stefnats I built my own SDK for NodeJS, requests look like this when using it:

const events = await amzSDK.request({
  region: "eu",
  type: "listFinancialEvents",
  queryParams: {
      PostedAfter: (new Date(fromDate)).toISOString(),
      PostedBefore: (new Date(toDate)).toISOString() 
  },
  accessToken: mwsAccountConfig.accessToken,
  iamUserAuth: auth,  
  bottleneckConfig: {
      ...auth.redisAuth
}

The SDK is currently private but I'm open for contributors :)

[stefnats]

I don't have that many ideas left and I think Amazon needs to help out. A quick stupid idea, are you URL encoding the next token and have you tried to base64 encode it?

[cgaugel]

Same problem here. It was working some weeks ago, now I am stuck here as well.. @parvathm fix this!

[fernlop]

@stefnats yes it gets URL encoded and it's already Base64 encoded. @cgaugel Did you open a case for this already? It's their basic excuse if they can't fix it quickly.

[cgaugel]

@fernlop , I just opened a case and submitted a new bug issue here: https://github.com/amzn/selling-partner-api-models/issues/384 because it is regarding another API endpoint than yours.

Hopefully they will fix this asap.

Hi all,

We are looking into this issue. @fernlop if you have already opened a case with above details please share case id.

Thanks, Parvathm, Selling Partner API Developer Support.

[fernlop]

@parvathm No I didn't create a ticket for this problem yet. Would this help organize the issues for you? Could you provide use a time window for this issue, maybe you already assigned it to a sprint :)

[parvathm]

Hi @fernlop,

Yes, if open a case and provide us request id, time stamp and any relevant data for which you are receiving error it helps us to identify the issue quickly and come up with ETA.

Thanks, Parvathm Selling Partner API Developer Support.

[cgaugel]

Still not fixed.

Hello,

The code changes for this issue have been deployed. Can you please try making the request with NextToken and let us know if the issue is resolved?
