Column, parameter, or variable #1: Cannot specify a column width on data type text.

I get this error when running Update-Migration.

///Error message Start

Applying migration ‘20200906170827_V1.0.0.1’. Failed executing DbCommand (8ms) [Parameters=[], CommandType=‘Text’, CommandTimeout=‘30’] CREATE TABLE [AccountGroups_DBSet] ( [GroupName] TEXT(50) NOT NULL, [GroupParent] TEXT(50) NULL, [BalanceSheetSide] TEXT(255) NULL, [Description] TEXT(255) NULL, [IsHidden] INTEGER NOT NULL, [GroupEnd] TEXT(50) NULL, [IsUnderBudgetControl] INTEGER NOT NULL, [BudgetAmount] TEXT(64) NULL, [IsUnderLocationControl] INTEGER NOT NULL, [Location] TEXT(50) NULL, [TxnID] TEXT(36) NOT NULL, [SearchKey] TEXT(150) NULL, [RecordVersion] INTEGER NOT NULL, [CreatedBy] TEXT(50) NOT NULL, [LastUpdatedBy] TEXT(50) NULL, [CreatedOn] TEXT(48) NOT NULL, [LastUpdatedOn] TEXT(48) NULL, [Company] TEXT(100) NULL, CONSTRAINT [PK_AccountGroups_DBSet] PRIMARY KEY ([GroupName]) ); Microsoft.Data.SqlClient.SqlException (0x80131904): Column, parameter, or variable #1: Cannot specify a column width on data type text. at Microsoft.Data.SqlClient.SqlConnection.OnError(SqlException exception, Boolean breakConnection, Action`1 wrapCloseInAction) in …More stack trace omitted

But when I generate SQL Script using dbContext.Database.GenerateCreateScript(), the generated script is different and also works when creating database schema manually. Look at what SQL script saved in a file from the same migration looks like :

CREATE TABLE [AccountGroups_DBSet] ( [GroupName] nvarchar(50) NOT NULL, [GroupParent] nvarchar(50) NULL, [BalanceSheetSide] nvarchar(255) NULL, [Description] nvarchar(255) NULL, [IsHidden] bit NOT NULL, [GroupEnd] nvarchar(50) NULL, [IsUnderBudgetControl] bit NOT NULL, [BudgetAmount] decimal(18,2) NULL, [IsUnderLocationControl] bit NOT NULL, [Location] nvarchar(50) NULL, [TxnID] nvarchar(36) NOT NULL, [SearchKey] nvarchar(150) NULL, [RecordVersion] bigint NOT NULL, [CreatedBy] nvarchar(50) NOT NULL, [LastUpdatedBy] nvarchar(50) NULL, [CreatedOn] datetime2 NOT NULL, [LastUpdatedOn] datetime2 NULL, [Company] nvarchar(100) NULL, CONSTRAINT [PK_AccountGroups_DBSet] PRIMARY KEY ([GroupName]) ); GO

Looks like you are mixing SQLite and SQL Server migrations ??

You probably want to take a look at this doc pagehttps://docs.microsoft.com/en-us/ef/core/managing-schemas/migrations/providers?tabs=dotnet-core-cli, about managing migrations in a multi-database scenario.
