When tring to add an already created label to a Confluence page I get the above error. The full error text is:
GraphQL error: Exception while fetching data (/addLabels) : io.atlassian.platform.micros.asynchttp.ContextualMicrosHttpAsyncClient$ReadingResponseException: com.fasterxml.jackson.core.JsonParseException: Unexpected character ('X' (code 88)): expected a valid value (JSON String, Number, Array, Object or token 'null', 'true' or 'false') at [Source: UNKNOWN; line: 1, column: 2]
I have closed my browser and tried reloading the page and adding the label but the problem recurs.
Any advice on how to resolve?
