Magento 2 data migration table or view not found

Question

I'm migrating Magento 1.7.2 to Magento 2.3.4 with respect to Magento data migration documentation. However I'm getting below error after post processing.

SQLSTATE[42S02]: Base table or view not found: 1146 Table 'mgn_' doesn't exist, query was: SELECT COUNT(*) FROM  mgn_

I'm unable to figure out issue, since error comes with prefix alone and no table is mentioned.

[WARNING]: Mismatch of entities in the document: mgn_inventory_source_item Source: 3311 Destination: 3307 [WARNING]: Volume Check failed

[INFO][mode: data][stage: data migration][step: PostProcessing Step]: started 92% [=========================>--] Remaining Time: 1 sec In Mysql.php line 110:

Issue is reproducible in Magento 2.3.4 only. I have created issue in [github][1] and it has been addressed.
