23100	IllegalArgumentException while trying to open custom WMTS imagery	anonymous	team	"==== What steps will reproduce the problem?
1. Create a custom WMTS image layer, such as [https://tucbs-public-api.csb.gov.tr/csb_cdp_im_wmts?request=GetCapabilities&service=WMTS here] or [https://kentrehberi.izmir.bel.tr/arcgis/rest/services/Rehber/CbsRehberGeo/MapServer/WMTS/1.0.0/WMTSCapabilities.xml here]
2. Open image layer

==== What is the expected result?
The image layer should open up perfectly with no errors, as I had used before.
==== What happens instead?
An java error pops up, with no useful end-user information whatsoever.
==== Please provide any additional information below. Attach a screenshot if possible.
