Angular CLI Migrated to integrated Nx Monorepo getting several type mismatch errors (error...

I recently moved my Angular CLI to NX workspace monorepo and after fixing all the import errors, it compiled and works as before. However I have over 100 type error, and I have tried to fix individually but it seems to be creating more issues. Here are some examples:

'myvariable' is possibly 'null'.
Type 'null' is not assignable to type 'IMyInterface'.
Type 'string | null' is not assignable to type 'string'.
Type 'null' is not assignable to type 'SafeHtml'.
Type 'Observable<(myType| null)[]>' is not assignable to type 'Observable<myType[]>'.
Type 'MatTableDataSource<T, MatTableDataSourcePaginator>' is not assignable to type 'MatTableDataSource<never, MatTableDataSourcePaginator>'.
Type 'T[]' is not assignable to type 'never[]'.
Type 'T' is not assignable to type 'never'.
Type 'any' is not assignable to type 'never'.


Nearly every .ts file gives me an error in regards to type. I have tried turning off strict

"forceConsistentCasingInFileNames": false,
"strict": false,
"noImplicitReturns": false,
"noFallthroughCasesInSwitch": false,
...
"angularCompilerOptions": {
"strictInjectionParameters": false,
"strictInputAccessModifiers": false,
"strictTemplates": false
}


Has anyone had this issue before? It is a big project so I cannot include all the code. Is there a way to fix this issue for all or do I have to take each error and fix individually?
