Hi,
I'm facing the situation where I need to use previously retrieved refresh_token to ask for new revresh token in Jira Tempo data query.
Script below works fine in case I enter refresh token manually (line- refresh_token = "zzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzz"],)
In real world it should change dynamically so that previously retrieved refresh token is used to ask next one.
I tried to substitute this line with reference to relevant field in the same table ( refresh_token = Q2{4}[Value], Q2 is query name) and during this I will get error "Expression.Error: A cyclic reference was encountered during evaluation." - what is understandable as I refer to the same table.
Any ideas how to resolve this issue? I have not find any way to store this value separately in Power Query or in Parameters. Any way of using variables here?

headers = [#"Content-Type" = "application/x-www-form-urlencoded", #"Accept" = "*/*"],
postData = [grant_type = "refresh_token",
client_id = "xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx",
client_secret = "yyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyy",
redirect_uri = https://cccccccccc.ee,
refresh_token = "zzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzz"],
response = Json.Document(Web.Contents(url,
[
Headers = headers,
Content = Text.ToBinary(Uri.BuildQueryString(postData))
])),
#"Converted to Table" = Record.ToTable(response)
in
#"Converted to Table"

Neither Power BI nor Power Query have any memory. Whenever you hear them say "variable" or "parameter" you need to mentally translate that as "immutable constant"
The only way I know how to handle this is to brute force it and ask for the initial token over and over again, completely ignoring the refresh tokens.
