No resource shown in My resource list after uploading widgets and mashup

[kushagrasrivastva-NEC]

There are no widgets and mashups shown in my resource list. Even after uploading it manually the widget gets uploaded but its not visible on My Resource list. After uploading it again it shows error as "widget already exist". I have deployed wirecloud from docker and integrated postgres database. Do I have to enable any settings in wirecloud so that widgets and mashup can be displayed. Also, it shows me the message on My Resource list and Widget as shown in screenshot.

Please find the wirecloud and postgres section which I am using in docker-compose.yml file

Please find the settings.py file. I tried running it with Haystack default search configuration given in "https://wirecloud.readthedocs.io/en/stable/installation_guide/#whoosh-configuration" but still with same error.
