Requesting HistoricalPricing.Summaries does not work for RICs containing "/" when using Eikon

When requesting RICs that contain "/" characters e.g. "aUSCCORYE/A" the result is a "404 page not found" error. This works using Workspace but does not work when using Eikon (4.0.64012)

I Modified Example "2.1.01-HistoricalPricing-Summaries" to reproduce this:

var response = Summaries.Definition("aUSCCORYE/A")
.Interval(Summaries.Interval.P3M)
.GetDataAsync().Result;

The RDP.log shows encoded instrument name

Method: GET, RequestUri: 'http://localhost:9060/api/rdp/data/historical-pricing/v1/views/interday-summaries/aUSCCORYE/A?interval=P3M&#39;

Tested with "Refinitiv.Data Library beta 5" for .net.

@martin.grunwald Thanks for your question and sorry to hear about your issue. It is infact an escaping issue as the historical pricing endpoint is being hit which is a URL with some querystring parameters - obviously such rics with a / character are not being interpreted correctly so we need to use the escaped charset for the / which is %2F - please see the following

rd.get_history("aUSCCORYE%2FA")

I hope this can help.

I tried the to manually "pre encode" the RIC and got the corrected result.

This obviously raises the question, how can I find out whether the RDP library is connected via Workspace or Eikon?

Hi @martin.grunwald

I just tested against my Desktop Session using the following

response = Summaries.Definition("aUSCCORYE/A").Interval(Summaries.Interval.P3M)
                                              .GetData();

And received the following response:

I reported this to the desktop team awhile back and based on what I can now see, the fix is in. However, the fix may have been applicable only to the Workspace proxy. I will confirm.

The Data Library does not distinguish between desktop connections into Workspace vs Eikon. It comes down to what you are running. I assume you are running Eikon given your original post.

I tested with both comparing the example with the exact parameters I was using in my application. Looking at the RDP.log I noticed the logged requests still differed. The only possible explanation I have for this behavior is that I am using the .net framework 4.8 and the example is using .net 6 and some underlying .net class behaves slightly different when it comes to encoding or stringifying the url.

For now I implemented a workaround where I always try the encoded version in case the non encoded version failed.

Hi @martin.grunwald,

Thanks for the logs.

In short, I was unable to replicate the issue you found. To make sure we're on the same page, I created a brand new .Net 4.8 project. I'm testing with Refinitiv Workspace, however, I don't think the issue is related to the session but rather the failing of escaping the embedded slash (/).

For example, here is my .Net 4.8 code:

var response = Events.Definition().Universe("aUSCCORYE/A")
                                  .Count(10)
                                  .EventTypes(Events.EventType.quote, Events.EventType.trade)
                                  .GetData();

Before the request is sent into the backend, this is what my URL looks like in the logs:

http://localhost:9001/api/rdp/data/historical-pricing/v1/views/events/aUSCCORYE%2FA?count=10&eventTypes=quote%2Ctrade

In preparation for this URL, the actual code that is escaping the slash looks like this:

var result = System.Uri.EscapeDataString("aUSCCORYE/A");  // Returns: aUSCCORYE%2FA

Comparing our logs, we're both using the same version:

Me:

2023-10-26 10:50:14.8368|Info|Refinitiv.Data.Initializer|1|Library version: 1.0.0-beta5
2023-10-26 10:50:14.8368|Info|Refinitiv.Data.Initializer|1|.Net runtime: 4.0.30319.42000
2023-10-26 10:50:14.8368|Info|Refinitiv.Data.Initializer|1|.Net version: 4.8.4645.0

You:

2023-10-25T17:48:44InfoRefinitiv.Data.InitializerLibrary version: 1.0.0-beta5
2023-10-25T17:48:44InfoRefinitiv.Data.Initializer.Net runtime: 4.0.30319.42000
2023-10-25T17:48:44InfoRefinitiv.Data.Initializer.Net version: 4.8.9181.0

The only thing I can suggest you try is the above code segment that escapes the (/) just to make sure it responds as expected - you should be getting the slash properly expanded. Please confirm.

You do have a workaround and you should be able to do something like this:

var response = Events.Definition().Universe(System.Uri.EscapeDataString("aUSCCORYE/A"))
                                  .Count(10)
                                  .EventTypes(Events.EventType.quote, Events.EventType.trade)
                                  .GetData();

One this that is confusing to me is when you explicitly request for "aUSCCORYE%2FA", it properly expands within the logs! That is:

http://localhost:9001/api/rdp/data/historical-pricing/v1/views/interday-summaries/aUSCCORYE%252FA?interval=P1D&count=10&sessions=normal'

%2FA successfully expands to %252FA! Yet "/" didn't expand.

I also find this "double encoding" confusing. I think it is not a language setting. I am running windows using the german local, but I don't see how the "/" would make a difference.

The System.Uri.EscapeDataString() suggestions is the fallback I am currently using.
