Problems creating a news post when a list item is created

(0) Share

Report

Posted on by Collinjay

I found this solved post about creating a news post when a list item is created and am trying to implement it. Screenshots of my entire flow are below. But I'm running into two issues.

Every time I run the flow, two pages are created. I'll get something like Test 01.aspx and Test–01.aspx
Every time I run the flow and have dynamic content in the 'innerHTML' (the yellow highlighted part in the second screenshot) the flow fails at the last action. I get a BadGateway error. Below the screenshots is the output of the error.

Any insight would be appreciated.

Tagging @Expiscornovus since he created the original solution I'm working off of.

Hi @Collinjay,

Are you escaping the quotes in the dynamic content you are using within the innerHTML property? Can you also share the HTML you are using in your test?

Hi @Expiscornovus,

I believe I'm escaping the quotes... Below is everything within the 'body' field, including dynamic content within the innerHTML property.

At this point, I'm testing the flow with text only in the SharePoint list form — so the html I'm using is something like <div>Lorem ipsum</div> or <p>Lorem ipsum</p>.

{ "LayoutWebpartsContent":"[{\"id\":\"cbe7b0a9-3504-44dd-a3a3-0e5cacd07788\",\"instanceId\":\"cbe7b0a9-3504-44dd-a3a3-0e5cacd07788\",\"title\":\"\\n Title area\\n \",\"description\":\"\\n Title area description\\n \",\"audiences\":[],\"serverProcessedContent\":{\"htmlStrings\":{},\"searchablePlainTexts\":{},\"imageSources\":{\"imageSource\":\"https://cdn.hubblecontent.osi.office.net/m365content/publish/f9acda13-4460-426f-b4d9-5fb9b34b47d0/613871602_super.jpg\"},\"links\":{},\"customMetadata\":{\"imageSource\":{\"width\":2048,\"height\":1152}}},\"dataVersion\":\"1.4\",\"properties\":{\"imageSourceType\":2,\"title\":\"@{triggerOutputs()?['body/Title']}\",\"textAlignment\":\"Left\",\"showPublishDate\":true,\"authors\":[],\"showTopicHeader\":true,\"authorByline\":[],\"layoutType\":\"FullWidthImage\",\"titlePlaceholder\":\"Name your news post\",\"topicHeader\":\"News & Notices\",\"enableGradientEffect\":true,\"imgHeight\":1152,\"imgWidth\":2048,\"translateX\":58.70870870870871,\"translateY\":49.122807017543856},\"containsDynamicDataSource\":false,\"reservedHeight\":228}]", "CanvasContent1":"[{\"controlType\":4,\"id\":\"1212fc8d-dd6b-408a-8d5d-9f1cc787efbb\",\"position\":{\"controlIndex\":1,\"sectionIndex\":1,\"sectionFactor\":8,\"zoneIndex\":1,\"layoutIndex\":1},\"addedFromPersistedData\":true,\"innerHTML\":\"@{triggerOutputs()?['body/Article']}\"},{\"position\":{\"controlIndex\":1,\"sectionIndex\":2,\"sectionFactor\":4,\"zoneIndex\":1,\"layoutIndex\":1},\"controlType\":3,\"id\":\"1856c2ad-84c5-43c3-8f12-f353dbbd8f5b\",\"webPartId\":\"8c88f208-6c77-4bdb-86a0-0c47b4316588\",\"reservedHeight\":424,\"reservedWidth\":364,\"addedFromPersistedData\":true,\"webPartData\":{\"id\":\"8c88f208-6c77-4bdb-86a0-0c47b4316588\",\"instanceId\":\"1856c2ad-84c5-43c3-8f12-f353dbbd8f5b\",\"title\":\"News\",\"description\":\"Show news posts from one or more sites in a variety of layouts.

Hi @Collinjay,

What settings did you use for the Article column in your source list? I used a Multiple lines of text without any additional settings (like Rich Text).

I just tested a similar setup and I got this as the end result.

The payload I used is slightly different. I wanted to start simple to see if the approach still works. Maybe you can test it with the same setup?

{ "LayoutWebpartsContent":"[{\"id\":\"cbe7b0a9-3504-44dd-a3a3-0e5cacd07788\",\"instanceId\":\"cbe7b0a9-3504-44dd-a3a3-0e5cacd07788\",\"title\":\"\\n Title area\\n \",\"description\":\"\\n Title area description\\n \",\"audiences\":[],\"serverProcessedContent\":{\"htmlStrings\":{},\"searchablePlainTexts\":{},\"imageSources\":{\"imageSource\":\"\"},\"links\":{},\"customMetadata\":{\"imageSource\":{}}},\"dataVersion\":\"1.4\",\"properties\":{\"imageSourceType\":2,\"title\":\"Test\",\"textAlignment\":\"Left\",\"showPublishDate\":false,\"authors\":[{\"id\":\"\",\"upn\":\"\",\"email\":\"\",\"name\":\"\",\"role\":\"\"}],\"showTopicHeader\":false,\"authorByline\":[\"\"],\"layoutType\":\"CutInShape\",\"titlePlaceholder\":\"Name your news post\",\"topicHeader\":\"\"},\"reservedHeight\":356}]","CanvasContent1":"[{\"controlType\":4,\"id\":\"1212fc8d-dd6b-408a-8d5d-9f1cc787efbb\",\"position\":{\"controlIndex\":2,\"sectionIndex\":1,\"sectionFactor\":12,\"zoneIndex\":1,\"layoutIndex\":1},\"addedFromPersistedData\":true,\"innerHTML\":\"@{triggerOutputs()?['body/Article']}\",\"emphasis\":{}},{\"controlType\":0,\"pageSettingsSlice\":{\"isDefaultDescription\":true,\"isDefaultThumbnail\":true}}]","Title":"@{triggerOutputs()?['body/Title']}"}

Also worth mentioning is that the Content-Type header I used has the odata=nometadata value (in this test, but also in my original post back in 2021).

{ "Accept": "application/json;odata=verbose", "Content-Type": "application/json;odata=nometadata" }

Hi @Expiscornovus,

I updated my flow to match your suggested setup and tested a few times. It both worked and didn't work.
It worked when the Article field was set to 'Multiple Lines of Text' and 'Rich Text' was turned off.
It did not work when Article field was set to 'Multiple Lines of Text' and 'Rich Text' was turned on.

I'm hoping to make this flow work with Rich Text turned on. I have a list of nearly 4000 items that I'm moving to a new site, and I want these 4000 items to become pages on the destination site. All these items are coming into the destination site with html in the Article field. Is this something I can accomplish with this flow?

Hi @Collinjay,

Just to double check. Can you explain why that Rich Text is a requirement?

Earlier you shared that you where using HTML tags as input directly in the multi line field. In that case you wouldn't need Rich Text, correct?

In the meantime I will have a look if I can get it working with Rich Text. It might be that some conversion is required to turn the rich text into valid HTML again.

Hi @slawo88,

Like mentioned in my previous reply. I would suggest to use a multiples lines of text field in the CMS source list with Rich Text disabled.

There is no point in using Rich Text if the aim is to write the HTML yourself in the field.
