When server returns unexpected error with a string, gocb.ExecuteSearchQuery returns json unmarshal error

with gocb 1.4, gocbcore v7,
When fts query server returns error like this

search request rejected","request":{"ctl":

{"consistency":null,"timeout":9499}

,"explain":true,"facets":null,"fields":["*"],"from":0,"highlight":

{"fields":null,"style":null}

,"includeLocations":false,"pindexNames":["ftsIndex_6dc7bf54169cbbda_f4e0a48a","ftsIndex_6dc7bf54169cbbda_18572d87"],"query":

{"query":"SampleValue1"}

,"size":10,"sort":["-_score"]},"status":"fail"}

gocb.ExecuteSearchQuery returns "json: cannot unmarshal string into Go struct field searchResponse.status of type gocb.SearchResultStatus"

Expected: Go SDK needs to handle the case where server response can not be parsed as searchResponse.status rather than returning unmarshal error. maybe Go sdk needs to check why the server error is considered as string type.
