WireMock Setting 'SaveMappingToFile' raising cast object to type error

[jmontalto01]

Describe the bug

I am using wiremock docker compose example with ProxyAndRecordSettings (command "--ProxyURL" ) and setting "--SaveMappingToFile", "true". It raises the following error when browsing to http:https://localhost:9091/__admin/mappings

{"Status":"Unable to cast object of type 'WireMock.ResponseProviders.DynamicResponseProvider' to type 'WireMock.ResponseBuilders.Response'."}

Expected behavior:

Load mapping files

Test to reproduce

Docker Compose file:

version: "3.8"

services:
wiremock:
image: sheyenrath/wiremock.net
ports:
- "9091:80"
volumes:
- ./wiremock/mappings:/app/__admin/mappings
command: ["dotnet", "wiremock-net.dll", "--Urls", "http:https://*:80", "--ReadStaticMappings", "true", "--AllowPartialMapping", "true", "--WireMockLogger", "WireMockConsoleLogger", "--ProxyURL", "https://api.hub24.com.au/epi/epiportfolio.asmx", "--SaveMapping", "true", "--SaveMappingToFile", "true"]

@jmontalto01 Can you provide your (static) mapping json file(s)?

[jmontalto01]

Hi,
There was no static mapping files. Folder was empty so I would expect an empty list to return when browsing to http:https://localhost:9091/__admin/mappings. At the time the error is raised it does then create a mapping json file on my drive which I have supplied below together with the wiremock log which gives more details of the error.

Wiremock Log:
wiremock log.txt

mapping file at the time of error returned in browser:

@jmontalto01 I think I found the issue, a new version from the NuGet + Docker will be released shortly.

This will be version 1.3.10

I'll close this now, in case it is not solved. just comment to this issue.
