I have a list with a column of images, I always want to get the thumbnailRenderer parameter in the sharepoint rest api response sometimes i get.
my query is:
https://testttr.sharepoint.com/sites/testadmin/_api/web/lists/getbytitle('Assets')/items?$select=Image
"Image": "{\"fileName\":\"12.jpg\",\"serverRelativeUrl\":\"/sites/testadmin/SiteAssets/Lists/bc4474ef-c463-4645-9561-ed3972135070/12.jpg\",\"id\":\"5768aaa4-9c33-4c5b-b17d-4bcf62fe2c4f\",\"serverUrl\":\"https://testttr.sharepoint.com\",\"thumbnailRenderer\":{\"spItemUrl\":\"https://testttr.sharepoint.com:443/_api/v2.1/drives/b!GtlpUBbcgkW_CHn3DwqYuAqWL0zDWtdEi1xPlBGSu7bE19ol3o3bk5f2f3R5hD0A5zU1Ze/items/1257365ALY702EDFGVJUFOM44LNGLC7KLZ5RP4LCP\",\"fileVersion\":2,\"sponsorToken\":\"L3NpdGUYQ4A2JH647443Rlc3RsYW5kaW5nL0xpc3RzL0Fzc2V0c3xJbWFLMF5x\"},\"type\":\"thumbnail\",\"fieldName\":\"Image\",\"fieldId\":\"0c537600-6d7f-42b2-930e-aedd2fHJ43E2GYH\"}"
