Exchange Rate Job Queue Error

Posted on by spinky

Hi,

I have a bit of a problem with the a Job Queue to update Exchange Rate daily. It is working temperamentally and I don't know where to trace the source of the problem to, so any assistance would be greatly appreciated.

When the Job Queue errors it comes up with this error:

The remote service has returned the following error message:

Connection to the remote service could not be established.

The remote server returned an error: (400) Bad Request.

Service URL:

https://query.yahooapis.com/v1/public/yql?q=select%20*%20from%20yahoo.finance.xchange%20where%20pair%20in%20(%22AUDCAD%22,%22AUDCHF%22,%22AUDEUR%22,%22AUDGBP%22,%22AUDHKD%22,%22AUDJPY%22,%22AUDNZD%22,%22AUDSGD%22,%22AUDUSD%22)&env=store://datatables.org/alltableswithkeys

When this error occurs I can't even view the Currency Exchange Rate Service card for this service as it comes up with the error:

A call to System.Xml.XmlReader.Create failed with this message: The remote server returned an error: (400) Bad Request

This does not happen all the time and in testing it can error then 2 minutes later run fine, then error in 10 minutes. I don't really understand why it is being so unpredictable. Is this possibly a web service issue rather than a NAV issue.

Any help appreciated.

Hi,

400 Bad request error is that the server which your trying to send some request must be probably incorrect and server cannot understand the request. Are you calling an external API or doing some real time integration by calling some web url?

Due to some error or missing content in the other website server the request that you are trying to make through HTTP is failing. You need to check that. Also you need to check your customized code.

Hi Spinky,

I have been playing with the web services. When you are calling web-service from dynamics NAV use Try Function. On function return parse the web-service response. You will find the status code. Like 200 in case of success, 400, when not found. So take appropriate action accordingly. In net shell you need to handle exception in C/AL.

Have a look at this. link.

This is how i did.

Thank you for the responses all.

It appears that the Yahoo Exchange Rate service has been discontinued so that's why it is no longer working!
