Converting JSON record to table issue

[ugurgulluev]

Hi all,

I am having an issue converting a JSON response to a table.

Here is my query (URLs and authorization removed for confidentiality):

let
    uri1 = "",
    url ="{
      ""syncedInstanceUri"":"&uri1&
    "}",
WebPageSourceFunc = () => Json.Document(Web.Contents("", [Headers=[Authorization="Basic", #"Content-type"="application/json"], Content=Text.ToBinary(url)])),
Ssource = Function.InvokeAfter (WebPageSourceFunc, #duration(0,0,0,1)),
    uri2 = Ssource[uri],
WebPageSourceFunction = () => Json.Document(Web.Contents(""&uri2&"/data?limit=50", [Headers=[Authorization="Basic"]])),
Sasource = Function.InvokeAfter (WebPageSourceFunction, #duration(0,0,0,1)),
    items = Sasource[items],
    #"Converted to Table" = Table.FromList(items, Splitter.SplitByNothing(), null, null, ExtraValues.Ignore),
    #"Expanded Column1" = Table.ExpandRecordColumn(#"Converted to Table", "Column1", {"ActivityId", "ActivityType", "ActivityDate", "ContactId", "IpAddress", "VisitorId", "VisitorExternalId", "EmailRecipientId", "AssetType", "AssetName", "AssetId", "SubjectLine", "EmailWebLink", "CampaignId", "ExternalId", "DeploymentId", "EmailSendType", "EmailAddress", "ContactIdExt"}, {"Column1.ActivityId", "Column1.ActivityType", "Column1.ActivityDate", "Column1.ContactId", "Column1.IpAddress", "Column1.VisitorId", "Column1.VisitorExternalId", "Column1.EmailRecipientId", "Column1.AssetType", "Column1.AssetName", "Column1.AssetId", "Column1.SubjectLine", "Column1.EmailWebLink", "Column1.CampaignId", "Column1.ExternalId", "Column1.DeploymentId", "Column1.EmailSendType", "Column1.EmailAddress", "Column1.ContactIdExt"})
in
    #"Expanded Column1"

This gives me the exact table that I need within the query, without any issues.

However, when I try to apply the query changes, I get the following error:

The field "items" of the record wasn't found.

Any idea on how to solve the issue?

Thanks,

Have you tried editing the script you have to remove the expanded column line and then go and manually see what columns there are to expand? See if that at least gives you somnething with no errors that you can apply? It might be an error with one of the rows json maybe?

let
uri1 = "",
url ="{
""syncedInstanceUri"":"&uri1&
"}",
WebPageSourceFunc = () => Json.Document(Web.Contents("", [Headers=[Authorization="Basic", #"Content-type"="application/json"], Content=Text.ToBinary(url)])),
Ssource = Function.InvokeAfter (WebPageSourceFunc, #duration(0,0,0,1)),
uri2 = Ssource[uri],
WebPageSourceFunction = () => Json.Document(Web.Contents(""&uri2&"/data?limit=50", [Headers=[Authorization="Basic"]])),
Sasource = Function.InvokeAfter (WebPageSourceFunction, #duration(0,0,0,1)),
items = Sasource[items],
#"Converted to Table" = Table.FromList(items, Splitter.SplitByNothing(), null, null, ExtraValues.Ignore),

in
#"Converted to Table"

Hi @gooranga1,

No luck.. 

I believe it applies the query after converting to table, and then unable to find in this step Source[items], since the query starts reading the code after "IN". 

However, I couldn't stilll figure out how to fix.

Best regards,

hi have you tried this? It sounds like there is no data being returned if the error message says it can't find items?

let
uri1 = "",
url ="{
""syncedInstanceUri"":"&uri1&
"}",
WebPageSourceFunc = () => Json.Document(Web.Contents("", [Headers=[Authorization="Basic", #"Content-type"="application/json"], Content=Text.ToBinary(url)])),
Ssource = Function.InvokeAfter (WebPageSourceFunc, #duration(0,0,0,1)),
uri2 = Ssource[uri],
WebPageSourceFunction = () => Json.Document(Web.Contents(""&uri2&"/data?limit=50", [Headers=[Authorization="Basic"]])),
Sasource = Function.InvokeAfter (WebPageSourceFunction, #duration(0,0,0,1)),
items = Sasource[items]


in
uri1

Any ideas all?

Hi @ugurgulluev ,

You can directly get the tables from the edit queries windows itself. After getting the data you can get the data you wanted from the edit queries windows itself.

Hi @Arul,

Thanks for the answer, but I am not sure if I got it correctly.

The query already generates the table I require, no problem there. But when I try to apply the query changes, I got the error I mentioned.

Can you please a little bit more explain?

Thanks,

Ugur

Thank you @Arul but this doesn't solve the issue.

"Let’s save the table by clicking Close and Apply in the Query Editor. This will enable us to generate the reports from the table, using the available templates."

This doesn't happen for me. This is the exact issue.
