Hello @s2_lf 

If you are using a custom module, which is updated in the schema that has tinytext field, find it and it will help resolve the issue.

If you are not using a custom module, please put the debug log in below file:

magento/framework/Setup/Declaration/Schema/Db/DefinitionAggregator.php:57

Hope it helps.

Hi @Meetanshi 

I answer to you and my answer has been deleted !

Nice !

I've find a solution but I had others issues.

I don't use module, just want to install Magento2 for the first time. Not friendly user :'(

I find installer here: https://magento.com/tech-resources/download

I try with no sample Data and with sample data -> same error.

I don't understand the difference between them.

I will try with new version (2.3.4)

Hope you could help me
