If you are using the GET method, you are limited to a maximum of 2,048 characters, minus the number of characters in the actual path, So i would suggest you to check the path length and your URL length. The Maximum length of URL is limited by the different browsers.
You can check this thread explaining the length issues for URL for different browser:
What is the maximum length of a URL in different browsers?
Maximum request URL size 4096 bytes, Applies to the Consumption tier only. Includes an up to 2048 bytes long query string
