TemplateModelException during JSON GET

I have the following code:

<#assign url_getUser = "https://DOMAIN.zendesk.com/api/v2/users?query=USER@COMPANY.com" />

<#assign response_user = http.client.request(url_getUser).header("Authorization", "Bearer "+ TOKEN).json().get() />

However, I keep getting the following error from the 2nd line:

Method "public final lithium.coreapi.webui.template.models.HttpClientResponseTemplateModel lithium.coreapi.webui.template.models.HttpClientRequestTemplateModel.get() throws freemarker.template.TemplateModelException" threw an exception when invoked on lithium.coreapi.webui.template.models.HttpClientRequestTemplateModel object "lithium.coreapi.webui.template.models.HttpClientRequestTemplateModel@6c4c48f".

If I change it to 

<#assign url_getUser = baseUrl + "users/"+ "ID" + ".json" />

It works fine. I am able to make the first call in call but it doesn't work in freemarker. Any ideas why?

    perk - Did you whitelist the domain in the admin?

    It is under Admin > System > HTTP Client [Enables you to specify allowed domains (where a request could be sent) as a comma-separated list.]

    Sorry this solution doesn't help. The baseURL also contains the same domain as the first request.

     

    Does anyone has any idea? This looks like a bug(?) in lithium handling of special characters in the URL or only accept certain strings in the URL? The expected response should be a JSONobject containing a JSON array.

    Yes, I do remember that there were certain issues with the special chars when we implemented one of our customizations, you need to drill down a bit more.

    I investigated the cause a bit deeper and here is something odd about Lithium:

     

    I have another line of code that contains a "?" and this works perfectly. So the character "?" is not an issue.

    <#assign url_getTicketsForUserID = baseUrl + "tickets.json?external_id=" + external_id />
    <#assign response_getTicketsForUserID = http.client.request(url_getTicketsForUserID).header("Authorization", "Bearer "+ response.content.access_token).json().get() />

    When I try this

    <#assign url_getUser = baseUrl + "users?query=abc" /> 

    It fails with the following error:

    Method "public final lithium.coreapi.webui.template.models.HttpClientResponseTemplateModel lithium.coreapi.webui.template.models.HttpClientRequestTemplateModel.get() throws freemarker.template.TemplateModelException" threw an exception when invoked on lithium.coreapi.webui.template.models.HttpClientRequestTemplateModel object "lithium.coreapi.webui.template.models.HttpClientRequestTemplateModel@66fc9c8f".    

     When I try the same URL in curl, I get a JSON Object back hence it is a valid command.

     

    The result should be: {"users":[],"next_page":null,"previous_page":null,"count":0}

     

    So what is going on here? Is there anyone from Lithium that can investigate with us on this? We are paying customer and need this roadblock to be resolved before we can launch Lithium.

    I think you may need to url encode the query parameter, try the following:

     

    <#assign url_getUser = "https://DOMAIN.zendesk.com/api/v2/users?" + "query=USER@COMPANY.com" ?url/>


    Hope this helps,

    I tried and a type mismatch happens. url can't be assigned to string. url_getUser isn't defined anywhere else.

     

    <#assign url_getUser = baseUrl +  "users/query=user@domain.com" ?url/>

    You have a space between the end quote (") and the question mark (?). Try removing the space. Also make sure baseUrl is a string. One other thing is to make sure only the query parameters are encoded. The following worked for me:

     

    <#assign baseUrl = "http://test.test.com/"/>
    <#assign url_getUser = baseUrl + "users?" + "query=user@domain.com"?url/>
    ${url_getUser}

    Hope this helps,

    Hey thanks for the suggestion.

     

    I tried:

     

    <#assign base = "https://our_domain.zendesk.com/api/v2/"/>
    <#assign url_getUser = base + "users?" + "query=username@company.com"?url/>
    <#assign response_user = http.client.request(url_getUser).header("Authorization", "Bearer "+ response.content.access_token).json().get() />

    and still received the same error:

     

    FreeMarker template error

     Method "public final lithium.coreapi.webui.template.models.HttpClientResponseTemplateModel lithium.coreapi.webui.template.models.HttpClientRequestTemplateModel.get() throws freemarker.template.TemplateModelException" threw an exception when invoked on lithium.coreapi.webui.template.models.HttpClientRequestTemplateModel object "lithium.coreapi.webui.template.models.HttpClientRequestTemplateModel@13d041cd". See cause exception. The failing instruction (FTL stack trace): ---------- ==> #assign response_user = http.client.r... [in template "retrieve-org-zendesk.ftl" at line 29, column 25]

     

    Totally at wits ends with what is going on in Lithium...

    Can you paste a sample response that you get from the API call here? I'd like to check if JSON parsing is failing here.  Also, please check the Content-Type header of the API response is returned as "application/json".

     

    You can also try to remove the .json() and print out the response string to see if you are at least able to get a response at all.

    Heyt YuriK,

     

    The sample JSON response would be: {"users":[],"next_page":null,"previous_page":null,"count":0} if you are do ?query=abc

     

    How should I print out the response when I remove json() ? There is no console in Lithium for output and I am relatively new with freemarker. 

     

    The endpoint sets the right content-type:

     Content-Type: application/json; charset=UTF-8

     

    Thanks for your help!
