Eikon Data API: Backend error failed to deserialize backend response
We get the following error when pulling headlines. Please help:
"Backend error. Failed to deserialize backend response. Expected valid JSON. Error: invalid character 'i' looking for beginning of value."
Our filter:
Language:LEN AND Source:SUGG AND ( Topic:GLOFIN OR Topic:TOPNWS ) NOT ( Source:TRAUT OR Source:ECLCTA OR Source:ECLTND OR Source:ECLPCM OR Source:ECLBFI OR Topic:ENT OR Topic:JOB OR Topic:SPO OR Topic:BACT OR Topic:STXOPS OR Topic:INTER OR Topic:MTPDF OR Topic:VID OR Topic:REP OR Topic:VEN OR Topic:INFO OR Topic:ORDIMB OR "NPL" OR Topic:WEA OR Topic:ENV OR Topic:TXT OR Topic:PCARD OR Topic:INSI OR Topic:RSUM OR Topic:PREV OR Topic:OBIT OR Topic:NMKR OR Topic:NEWR OR Topic:FILING OR Topic:ADVS OR Topic:AAA OR Topic:MEVN OR Topic:RCH OR Topic:PRO OR Topic:PPLMOV )
There mismatch error with "" characters in your filter ("NPL" should be 'NPL').
Try with this query string:
"Language:LEN AND Source:SUGG AND ( Topic:GLOFIN OR Topic:TOPNWS ) NOT ( Source:TRAUT OR Source:ECLCTA OR Source:ECLTND OR Source:ECLPCM OR Source:ECLBFI OR Topic:ENT OR Topic:JOB OR Topic:SPO OR Topic:BACT OR Topic:STXOPS OR Topic:INTER OR Topic:MTPDF OR Topic:VID OR Topic:REP OR Topic:VEN OR Topic:INFO OR Topic:ORDIMB OR 'NPL' OR Topic:WEA OR Topic:ENV OR Topic:TXT OR Topic:PCARD OR Topic:INSI OR Topic:RSUM OR Topic:PREV OR Topic:OBIT OR Topic:NMKR OR Topic:NEWR OR Topic:FILING OR Topic:ADVS OR Topic:AAA OR Topic:MEVN OR Topic:RCH OR Topic:PRO OR Topic:PPLMOV )"
It worked. Many thanks.
