Fragility of the API? in get_data raise RDError(-1, except_msg)
Working with Refinitiv Data Python library I have some bond titles for which I pull the Ultimate Parent Id in order to further query some data:
>>> import refinitiv.data as
>>> import pandas as pd
...
>>> ParentIDs
Instrument Ultimate Parent Id

However, if I pull the Primary Quote, I get the following error:
>>> RICs = rd.get_data(
... universe = ParentIDs['Ultimate Parent Id'].unique().dropna(),
... fields = ["TR.PrimaryQuote"]
... )
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
File "C:\Users\...\AppData\Roaming\Python\Python311\site-packages\refinitiv\data\_access_layer\get_data_func.py", line 126, in get_data
raise RDError(-1, except_msg)
refinitiv.data._errors.RDError: Error code -1 | Backend error. 400 Bad Request Requested universes: ['5051045063', '5057937159', '4295903254',

At a second attempt it worked.
- What does this error message mean?
- Is the API "fragile"? It also takes sometimes a very long time just to get some data (e.g. "Ultimate Parent Id")

@fabian.echterling Thanks for your question - so during busier periods of high load - occasionally some requests are dropped - the only real solution is to code defensively in a try-except structure and re-present the call - perhaps after a small sleep. I will contact the service team and see if there are any specific issues and report back. Could you also provide a full universe list to see if I can replicate or if there is some issue with the identifiers.
The API Limits for get_data are 10,000 datapoints per API call - so you are well within that. I hope this can help.

Thank you! That already explains it for me. Would be great if the Refinitiv infrastructure will be strong enough in the future to built reliable workflows.0
