GenerateChangeLog failed for one MySQL database

Hi, I have tried to generate change log for my MySQL schema but getting the below exception. I have tried the below things.
1.removed table names with more than 30 char length.
2. Removed all views and tried.
3. Used --diffType

my command is below:

    liquibase --changeLogFile=genChangeLog_MySchema.mysql.sql \
    --logLevel=debug \
    --logFile=MySchema1.log  \
    --includeSchema=true \
    --includeTablespace=true  \
    --diffTypes=tables,columns,indexes,foreignkeys,primarykeys,uniqueconstraints \
    generateChangeLog

I am using version 4.1.1 and openjdk 11.0.8.
Any help to solve this will be appreciated.
