couchbase.exceptions.ArgumentError: <TTL must be numeric,

Hi

I am using cb.upsert_multi(‘key’:‘value’) syntax to load my data from Oracle to Couchbase and ending up below errors :

Any pointer what I am doing wrong ?

File “/opt/conda/lib/python3.7/site-packages/couchbase/bucket.py”, line 1148, in upsert_multi
replicate_to=replicate_to)
couchbase.exceptions.ArgumentError: <TTL must be numeric, C Source=(src/typeutil.c,168), OBJ={‘K_ID’: 112053564, ‘K_NUMID’: 417979}>

thanks
