Unhandled Rejection (TypeError): Cannot read properties of undefined (reading 'open')

[Tyrell20]

Hi All
After starting, navigating to the service URL I get the following error:

`Unhandled Rejection (TypeError): Cannot read properties of undefined (reading 'open')
loadStoredCustomCharts
src/hooks/useCustomCharts.js:73
70 | * @type {StoredCustomChart[]}
71 | */
72 | const storedCustomCharts = JSON.parse(localStorage.getItem(STORE_NS) ?? '[]')

73 | const cache = await window.caches.open(STORE_NS)
| ^ 74 |
75 | // Calculate an unique list of sources to load
76 | // It also read caches storage and create a browser url for file sources`

No impact appears to be there on fuctionality, just close the error to take advantage of the tool
