Hello @Samya, 

Thanks for joining our community. 

That issue is happening because JSON_STORE format is VARCHAR(2), not VARIANT as required. 

Something you can try is to add a ConvertRecord processor before the PutDatabaseRecord. 
There, you can use a JsonTreeReader → JsonRecordSetWriter to reformat the content. In that way, the JSON_STORE field becomes a proper JSON object.

Something like this👆
