Dear all,
I'm trying to use Text Analysis Cognitive Services in Power BI Desktop, but I'm having this error since a long time, and I have tried some solutions but it did'n works.
Formula.Firewall: Query 'Coulmn' (step 'Invoked Custom Function') references other queries or steps, so it may not directly access a data source. Please rebuild this data combination.
I were following the steps excatly as it's listed in this tutorial link:
and I've visited Ken Puls blogg as it solved a similar problem posted by a regular visitor.
but it's not the same problem I have since my code does't contain a 'source' :
// Returns key phrases from the text in a comma-separated list
(text) => let
apikey = "API_KEY",
endpoint = "https://<custom-subdomain>.cognitiveservices.azure.com/text/analytics" & "/v2.1/keyPhrases",
jsontext = Text.FromBinary(Json.FromValue(Text.Start(Text.Trim(text), 5000))),
jsonbody = "{ documents: [ { language: ""en"", id: ""0"", text: " & jsontext & " } ] }",
bytesbody = Text.ToBinary(jsonbody),
headers = [#"Ocp-Apim-Subscription-Key" = apikey],
bytesresp = Web.Contents(endpoint, [Headers=headers, Content=bytesbody]),
jsonresp = Json.Document(bytesresp),
keyphrases = Text.Lower(Text.Combine(jsonresp[documents]{0}[keyPhrases], ", "))
in keyphrases
Any Suggestions please!

@Icey ,
Unfortunately, I'm not a pro user.

@Heyam seems like your firewall issue is resolved? correct? Do you any error when you preview in power query?

Hi @Heyam ,
Please try this:
If this doesn't work, please try to create a custom column as fixed Text and try it again.
let
text = [comment]
apikey = "API_KEY",
endpoint = "https://<custom-subdomain>.cognitiveservices.azure.com/text/analytics" & "/v2.1/keyPhrases",
jsontext = Text.FromBinary(Json.FromValue(Text.Start(Text.Trim(text), 5000))),
jsonbody = "{ documents: [ { language: ""en"", id: ""0"", text: " & jsontext & " } ] }",
bytesbody = Text.ToBinary(jsonbody),
headers = [#"Ocp-Apim-Subscription-Key" = apikey],
bytesresp = Web.Contents(endpoint, [Headers=headers, Content=bytesbody]),
jsonresp = Json.Document(bytesresp),
keyphrases = Text.Lower(Text.Combine(jsonresp[documents]{0}[keyPhrases], ", "))
in
keyphrases

Thank you @Icey , your second suggestion worked with well, but it turn an error when apply it.
Please notice that I'm working on 20,000 records (rows), and planning to implement the query on 130,000 records later on.
Is it a problem? while I'm calling API version v2.1 endpoint from the code, v2.1 has no maximum limit !
And if I copied the Endpoint as it's in Azure portal, it doesn't contain the location like http://westus.domain.
