If the type is internal you have to add the flag --parseInternal, if its from a dependency use --parseDependency

swag init --parseDependency --parseInternal

Hi all!) I have the same issue with: swag init --parseInternal --parseDepth 2 -g path/to/my/main.go

Output: cannot find type definition: sql.NullTime

Maybe there are other solutions to resolve this issue?

I have another solution, make the .swaggo file among with your go.mod Content inside .swaggo will be

replace JsonNullBool boolean
replace JsonNullNumber integer
replace JsonNullNumberStr string
replace decimal.NullDecimal number

maybe your case will be replace sql.NullTime string

Thanks for an advice) I found a the better solution by adding swaggertype:"string" tag for selected sql.NullTime type. Take a look here --> https://github.com/swaggo/swag#use-swaggertype-tag-to-supported-custom-type

It works well for me :+1:
