[Bug]: Swashbuckle.AspNetCore.Cli v.6.7.0 doesn't generate format of the property

[AndriiBlandov]

Describe the bug

In generated swagger.jwon property description object doesn't contain "format"

Expected behavior

"components": {
"schemas": {
"WeatherForecast": {
"type": "object",
"properties": {
"date": {
"type": "string",
"format": "date-time"
},

Actual behavior

"components": {
"schemas": {
"WeatherForecast": {
"type": "object",
"properties": {
"date": {
"type": "string",
"format": "date-time"
},

Steps to reproduce

Generate swagger.json for ASP.NET Core Web Api using class with DateTime property

Exception(s) (if any)

No response

Swashbuckle.AspNetCore version

6.7.0

.NET Version

8.0.303

Anything else?

With version 6.6.2 everything works as expected

Please provide a minimal reproducible example as a GitHub repository that demonstrates the issue you're experiencing so we can look into this further.

It's hard to work backwards from the output to determine what about the input has seemingly missed our test coverage.

[martincostello]

Without a repro to go off, looking at the diff since 6.6.2 my guesses for where a regression could have been introduced are #2803, #2941 or #2980.

False alarme, I am sorry, there was a problem with dependencies in that used Swachbackle as well but was not updated to latest version.

In my case this is because I had a mismatch of Swashbuckle versions:

<PackageReference Include="Swashbuckle.AspNetCore" Version="6.7.1" />
<PackageReference Include="Swashbuckle.AspNetCore.Newtonsoft" Version="6.5.0" />
