Bug in APEX application export with PWA support?

Hi,

I'm facing a problem while importing an APEX 21.2 application. APEX reports the following error: "ORA-06550: line 2, column 1: PLS-00306: wrong number or types of arguments in call to 'CREATE_FLOW'". The cause for this is, that the export sets a parameter "p_pwa_manifest_background_color" for the wwv_flow_api.create_flow-call but the parameter of this procedure is named "p_pwa_manifest_bg_color". It is pretty obvious that this is a bug in APEX exporter. I'm relatively new to the APEX world, so I'm not sure, if this is the right place to report this problem. So if I'm wrong here, I would appreciate a hint where to put stuff like this. Thanks.

Regards

Michael
