plugin: input.mysql: 'innodb_available_undo_logs' different datatype

[eraac]

System info:

Telegraf 1.15.2 (git: HEAD cd037b4)
plugin: inputs.mysql (one for master and one for slave)
influxdb: v2-rc2 - I didn't have any issue with v2-beta16

Expected behavior:

Field innodb_available_undo_logs should have the same data type

Actual behavior:

Field innodb_available_undo_logs has different data type (int for master, float for slave)

Additional info:

master: SHOW GLOBAL STATUS:

innodb_available_undo_logs: 128

slave: SHOW GLOBAL STATUS:

innodb_available_undo_logs: 18446744073709551615

error

2020-10-26T15:42:00Z E! [agent] Error writing to outputs.influxdb_v2: 500 Internal Server Error: internal error: unexpected error writing points to database: partial write: field type conflict: input field "innodb_available_undo_logs" on measurement "mysql" is type float, already exists as type integer dropped=8

Under outputs.influxdb_v2, I see a parameter influx_uint_support, does this solve the issue?
