I tried to add a Custom Signal for "Event: Get interactions with professional posts". It worked for a while, but when I went to edit the signal and add some more Post URLs, I get an error: "This Signal failed to execute: Invalid input. Please try again or contact support"
The "Invalid input" error when editing your Custom Signal for professional posts interactions is likely related to formatting issues with the Post URLs you're adding. Since this involves input formatting, please copy and paste the Post URLs you're trying to add into this chat so I can help troubleshoot the specific formatting issue. Common causes include: ** Incorrect URL format ** Extra spaces or hidden characters ** Missing quotes around URLs ** Syntax errors in the input field If you need further help after we review the URLs, you can request human assistance by clicking "Talk to a person."

The formatting issue is likely caused by missing quotes around your URLs and improper comma separation. Each URL should be enclosed in double quotes and separated by commas.
Try formatting like this: LBKS"[URL]", "[URL]", "[URL]", "[URL]"LBKSCommon fixes:
** Ensure each URL is surrounded by double quotes
** Remove extra commas at the end
* Check for hidden characters by pasting into a text editor
You can also paste your formatted URLs into JSONLint.com to validate the syntax before adding them to your Custom Signal.

The issue is with the parentheses in your URL format. You're using "[URL] ([URL])" but this creates invalid JSON syntax because parentheses aren't properly escaped.
Try one of these formats instead:
Option 1 - Just the URLs:
"[URL]", "[URL]", "[URL]"
Option 2 - Escape the parentheses:
"[URL] \([URL]\)", "[URL] \([URL]\)"
The parentheses need to be escaped with backslashes or removed entirely for valid JSON formatting. You can validate your syntax at JSONLint.com before adding to your Custom Signal.
Hi - Haydn R. Clay's Custom Signal for LinkedIn Post Interactions expects properly formatted post URLs (and sometimes only a single input field at a time). let me give you a method Create a column where each row has only one LinkedIn post URL In the Custom Signal input map that column. Make sure: One cell = one valid post URL (no commas, no multiple links). The link contains linkedin.com/posts. Remove any empty rows. Run the Signal again it should work without errors.
Or just a screenshot so I can understand what you mean
Hi Hadyn, thanks for reaching out! Do you mind trying to create a new signal where it's just a list with the commas, no quotes, and "/" at the end of each link? I tested this and was able to get the signal to work with two of your links, except I had "/" at the end. This is what I used in Post URLs: [https://www.linkedin.com/feed/update/urn:li:activity::7356239659615592448/](https:://www.linkedin.com/feed/update/urn:li:activity:7356239659615592448/), [https://www.linkedin.com/feed/update/urn:li:activity::7353702945101598720/](https:://www.linkedin.com/feed/update/urn:li:activity:7353702945101598720/)

Thank you! I see the error - but I also see 77 rows populated in the table. Was that there before?
77 were already populated. This was the one I created after you asked me to: https://app.clay.com/workspaces/466469/workbooks/wb_0t1asam8K8nwKH3GjxR/tables/t_0t1asamnrY7XDSkxzXS/views/gv_0t1asam3VJKdbJuosRc The 77 were populated when I had fewer Post URLs in the signal. Is there a limit it can take per workbook?
Hey Haydn, I just went into your table and fixed the signal. The issue was that for two of the links, a comma wasn't separating them, so it messed up the whole input sequence. You should be good to go!
Let me know if you have any questions!
Thanks! So, no limit on allowed Post URLs per signal?
Hi Haydn! Natalie here stepping in for Amit. There is a limitation around the 1,000 mark likely due to loading delays that occur with larger datasets. If you are close to using 1,000 Post URLs, I would suggest breaking it up into multiple signals. Let me know if you have further questions or need additional help! 😊
