Issues when loading component

[MatteoB]

I'm facing with some errors when my componet is loaded.
In Console I have these problems:

-Common.LocalForage:IndexedDB is NOT available

-ChartApi.Core:Cannot get studies_metadata, reason: Error: No available storage method found.

-:ChartApi.Core:Cannot update studies_metadata cache, reason: Error: No available storage method found.

-Cannot read property 'length' of null

How can I fix these kind of errors?

Thanks
