Hello @ranjit.talukdar

This issue is "TREP-1568" issue which has been fixed in ADS 3.2.1

TREP-1568; Invalid JSON if RMTES STRING Contains all NULL Characters
  RMTES_STRING fields in RWF containing all null characters (0x00) would not correctly display in JSON.

This issue occurs when ADS 3.2.0 receives null characters (0x00) for the RMTES string field from Elektron.

It can be occurred with any RICs and any string type Fields that got null string data

(0x00) from Market/Exchange or Feed.

we are using TREP 3.2.0

alternatively they should return a least a string encapsulated blank

Hello @ranjit.talukdar

Referring to this post, this issue has been fixed in ADS 3.2.1 L1. I did a quick test with ADS 3.2.1 L1, .FTSE returns data fine. Please upgrade your TREP to 3.2.1 L1 version.

My example .FTSE data from ADS 3.2.1L1 is shown below:

"THEO_LLDAT": null,
"ACT_FLAG1": null,
"ACT_FLAG2": null,
"ACT_FLAG3": null,
"ACT_FLAG4": null,
"ACT_FLAG5": null,
"GEN_VAL1": 6648.86,
"GEN_VAL2": 7730.28,
"GEN_VAL3": null,
"GEN_VAL4": 7689.57,
"GV1_TEXT": "TRI   ",
"GV2_TEXT": "Pr.Cls",
"GV3_TEXT": null,
"GV4_TEXT": "Of.Cls",
"NM_IND": "      ",
"SEQNUM": null,

thanks - we are planning an uopgrade of the infra but in the mean time an application is pushing to go live before we upgrade using data views.

could you help confirm for me the total list of fids affected by this issue?

many thanks

@Wasin Waeosri

appreciate if someone can respond on this one and provide a definitive list of the affected fids.

Thanks @Wasin Waeosri

but is it possible to provide a list of these FIDS? or do u mean it can actually affect any fid that might be blank on a particular day/time for whatever reason?
