Good day everyone.

We are currently experiencing a sync issue between bahmni (version 0.92) and odoo; in our failed events records, we have the 3 following recurring exceptions:

Exception 1: represents 80% of failed messages

`com.fasterxml.jackson.databind.JsonMappingException: Can not deserialize instance of java.lang.String out of START_OBJECT token`

Exception 2: represents 10% of failed messages

`java.lang.RuntimeException: warning -- Previous order id does not exist in DB. This can be because of previous failed events`

Exception 3: represents 10% of failed messages

`java.lang.RuntimeException: 'list' object has no attribute 'ids'`

For the most recurring failed event (i.e. Exception 1), there has been a PR on bahmni-erp-connect 0.93 (see: [https://bahmni.atlassian.net/browse/BAH-1212](https://bahmni.atlassian.net/browse/BAH-1212) and [BAH-1212 | Fixing order sync error if encounter has associatded coded obs related to order by angshu · Pull Reque](https://github.com/Bahmni/openerp-atomfeed-service/pull/33)) that addresses the issue. However, we are not yet ready to fully migrate to Bahmni 0.93; but thinking of updating only bahmni-erp-connect component to 0.93 to attempt to resolve the sync issue. We are concerned about potential unforeseen issues this might cause. Is it possible to use bahmni-erp-connect 0.93 with bahmni 0.92? Has anyone tried this before? What could be the possible issues to look out for?

It may work. Honestly we have not tested. Why not give it a shot in local?
