Store step has its own map file map-stores.xml.dist . Check if the record
<stores_map_file>etc/opensource-to-opensource/map-stores.xml.dist</stores_map_file>
is in you config.xml

[VijaySankhat]

Thanks for your response @victor-v-rad
Yes I have rename it as etc/opensource-to-opensource/map-stores.xml
And the content of

map-stores.xml is as below.

<map xmlns:xs="http://www.w3.org/2001/XMLSchema-instance" xs:noNamespaceSchemaLocation="../map.xsd">
    <source>
        <document_rules>
            <rename>
                <document>core_store</document>
                <to>store</to>

Your map-stores.xml is the same as original map-stores.xml.dist Anyway I've just migrated with command bin/magento migrate:settings path/to/config.xml without any problems

[VijaySankhat]

@victor-v-rad please provide some suggestions, if you have any.

[victor-v-rad]

This error happens when M1 or M2 use prefix in tables name. Please add your prefix in config.xml file in tags

<source_prefix />
<dest_prefix />

[Eddcapone]

I have used prefix but still get the same error.

[PurushothamanKrishnamoorthy]

@victor-v-rad : This issue is generating for both 2.3.4 and 2.3.5 . It was working fine for me month, Now I'm facing the same issue. I have updated map files, config files and prefix too. Can you suggest ways to debug this issue.

And I can see these fields are already ignored by default in maps.xml but why we are getting these error?

[PurushothamanKrishnamoorthy]

@victor-v-rad : I have ignore fields in map-stores.xml, it works but I'm getting below error:. Is that a right approach ?
