HTTP 500 when trying to open a file in OnlyOffice and Collabora

[coucoulala]

Describe the bug

I've setup Collabora and OnlyOffice as described here https://github.com/owncloud/ocis/tree/master/deployments/examples/ocis_wopi . When I try to open a Document in either OnlyOffice or Collabora an error is thrown. I checked https://ocis.ocis-wopi.released.owncloud.works and the issue exists there as well.

Steps to reproduce

Steps to reproduce the behavior:

1. Follow the instructions here: https://github.com/owncloud/ocis/tree/master/deployments/examples/ocis_wopi .
2. Upon trying to open either editor an error is thrown.

Expected behavior

The opening of the file in OnlyOffice / Collbora.

Actual behavior

Error.

Setup

Like here https://github.com/owncloud/ocis/tree/master/deployments/examples/ocis_wopi but with Authelia as external IDP instead of Keycloack.

Thanks for the report, I'll have a look.

Opening documents on https://ocis.ocis-wopi.latest.owncloud.works/ is perfectly possible (oCIS master), but as you described, it fails on https://ocis.ocis-wopi.released.owncloud.works/ (oCIS 1.15)

Took me also some time to notice, but the deployment changed. We renamed some variables in 222683d#diff-00f4b53022cf3b58e15026fe6107678c262c84901e8588d044984cf217212019 ( as part of #2811).

So if you use APP_PROVIDER_BASIC_GRPC_ADDR instead of APP_PROVIDER_GRPC_ADDR and APP_PROVIDER_BASIC_EXTERNAL_ADDR instead of APP_PROVIDER_EXTERNAL_ADDR, it also works with oCIS 1.15.0.
