Our application is using DSS API and sends quite many PriceHistory OnDemand requests.

During last week we have received twice following errors from Refinitiv (500 server error). As "customerrors" are turned off, we can see the details of error exactly with all internal details, see attachment:

error.txt.

You can rename the file to html format to see how error looks like. It's something wrong on your side.

Unfortunately it is impossible to reproduce directly. It just happens from time to time and our application is producing many different OnDemand requests using PriceHistory template, so it's not something specific to particular request. As on next day for example the same set of requests is successful.

Here are some other details:
