Random Charecters added to URL

[craftzneko]

What happened?

I had a previously working dashboard that had a Data link. Now characters are added to values. Data link looks like this

https://logic.azure.com/workflows/invoke?api-version=2016-06-01&GroupID=%EF%BB%BF%EF%BB%BF854032434532345344%EF%BB%BF

The group ID has this appended to it %EF%BB%BF%EF%BB%BF8540 and after it %EF%BB%BF

The data is fetch from a sql table and has no zero width charecters i have replaced the data in there to be sure. The data link looks like this

https://logic.azure.com/workflows/invoke?api-version=2016-06-01&GroupID=${__data.fields.AzureGroupID}

What did you expect to happen?

GroupID is inserted without random string charecters applied

I have found the problem but have no idea how this has happened between grafana updates. The dashboard has not been updated for over a year, but looking at the JSON at the link i see these appearing now. I suggest this is a bug that needs to be looked at why these appear, Recreating the link does NOT remove these, you need to modify the JSON directly

I've had this issue too, the characters appear to be zero width spaces (0xfeff). Manually removing these from the JSON also fixed it for me, thanks!
