Search criteria not working inside custom widget

Hi all,

I tried to use search criteria inside of a custom widget to get a specific record from a custom module but got the error message:
message: "Value for url is too long"
I wonder is there a way to use search criteria inside a custom widget? Thanks in advance!

code snippet:

// Build search criteria to filter for specific config record
const searchCriteria = {
"list_info": {
"search_criteria": {
"field": this.config.FIELD_NAME_KEY,
"condition": "is",
"value": this.config.CONFIG_RECORD_NAME
}
}
};

const inputData = encodeURIComponent(JSON.stringify(searchCriteria));
const fullUrl = `${this.apiBaseUrl}/${this.config.MODULE_API_NAME}?input_data=${inputData}`;
//const fullUrl = `${this.apiBaseUrl}/${this.config.MODULE_API_NAME}`
console.log("full url: ", fullUrl);
const options = {
url: fullUrl,
method: "get",
connectionLinkName: this.config.CONNECTION_NAME,
headers: { "Accept": "application/vnd.manageengine.sdp.v3+json" }
};
